abdomen muscles - Answer>>1. linea alba
subscapularis in cat - Answer>>on the anterior side of the shoulder, versus the supraspinatus and all the other muscles are only seen on the posterior side of the scapula/shoulder where the spine is -in front -below pectoralis minor, can't see it cat back muscles - Answer>>-spinotrapezius -acromiotrapezius -latissimus dorsi -clavotrapezius -clavodeltoid gluteus medius in cat - Answer>>This is a thick, short muscle almost entirely covered by the tensor facia latae, above gluteus maximus, larger than gluteus maximus gluteus maximus in cat - Answer>>in the human the gluteus maximus is bigger and covers whole hip, in the cat it's in between the gluteus medius and caudofemoralis, it is immediately superior to the caudofemoralis tensor fascia latae in cat - Answer>>underneath of it/deep is the vastus lateralis, sartorius is the small muscle above it that extends downward gastrocnemius in cat - Answer>>medial head- on the medial side lateral head- on the lateral side soleus in cat - Answer>>inferior to gastronemius muscle
~adductor magnus, gracilis, semimembranosus, semitendinosus, biceps femoris Calf muscles - Answer>>CALF MUSCLES-SUPERFICIAL gastrocnemius, soleus, plantaris masseter muscle in a human - Answer>>cheek/zygomatics (only 1) *think masticate meaning to chew masseter muscle in a cat - Answer>>zygomatics, chewing muscle sternocleidomastoid in human - Answer>>neck muscle (break up the word: sternum, clavicle, mastoid process which are the three points of attachment) sternomastoid in cat - Answer>>medial portion of sternocleidomastoid in humans, covers neck another name for clavobrachialis - Answer>>clavodeltoid (it is the most superior shoulder/arm muscle), think because it is apart of the arm and shoulder it is called "brachialis" for arm and "deltoid" for shoulder Chest muscles in a human vs. Chest muscles of a cat - Answer>>The cat has two additional muscles while humans only have pec major and minor Human (2)
-vastus intermedialis +1-sartorius -all 4 muscles merge to form the patellar tendon (on top of patella, largest sesmoid bone) rectus femoris in human - Answer>>-directly down the center (on the femur bone), has a white shiny appearance -quad muscle rectus femoris in cat - Answer>>sandwiched between vastus lateralis and vastus medialis, large thigh muscle vastus lateralis in human - Answer>>on lateral aspect down by knee, lateral to rectus femoris -quad muscle vastus medialis in human - Answer>>on medial aspect down by knee, lateral to rectus femoris -quad muscle vastus medialis in a cat - Answer>>thigh muscle, on the medial side of the rectus femoris (seperates vastus medialis and vastus lateralis) vastus intermedialis in human - Answer>>can only see it if you pop the tendon, located deep to rectus femoris in other words, underneath of rectus femoris -quad muscle, in cat it is vastus intermedius vastus intermedius in cat - Answer>>underneath of rectus femoris sartorius muscle in human - Answer>>-part of quad compartment/thigh/upper leg -crosses over thigh like a strap
-only flexor flexor muscle, originates above hip joint -long, strap like muscle that goes across the thigh and inserts into the tibial tuberosity -seperates quads from adductors -crosses 2 joints xiphihumeralis in cat only - Answer>>below pec minor, at the very bottom of the chest just above rectus abdominus and obliques external oblique in cat - Answer>>sides, love handles, outermost oblique muscle, under is internal oblique internal oblique in a cat - Answer>>underneath external oblique Tibialis anterior in humans - Answer>>lateral to tibial bone -anterior leg muscle -use tibia bone as landmark trapezius muscle in human - Answer>>along clavicle and abbuts against deltoid from occiput (back of head) down center of back, in the shape of a diamond goes up the back of the head to loosen up this muscle do shoulder rolls, upper back, lower back is latissimus dorsi muscles of the rotator cuff (4) - Answer>>attaches to the scapula, all insert into the humeral head, allow you to brush teeth and hair, women carry heavy purses which can mess up your rotator cuff -supraspinatus -infraspinous -subscapularis -teres minor
gluteus minimus in human - Answer>>-gluteal muscles that can only be seen when you peel the gluteus medius back, CAT DOES NOT HAVE THIS -deepest layer tensor fasciae latae/TFL in human - Answer>>-gluteal muscle, lateral side of the thigh, up next to sartorius on the lateral most side -located lateral to vastus lateralis muscle in the thigh- rotates hip out, located on the lateral side of the thigh -short muscle with long tendon -superior most quad muscle spinodeltoid in the cat - Answer>>descends lateral to supraspinatus (big muscle) on rotator cuff, above is acromiodeltoid in other words the spinodeltoid is below acromiotrapezius acromiodeltoid in the cat - Answer>>these musles make up the deltoid muscle in the human: acromiodeltoid is lateral/next to the spinodeltoid on rotator cuff acromiodeltoid and spinodeltoid are both above triceps brachii (long head and lateral head) clavobrachialis/clavodeltoid in the cat - Answer>>on top of acromiodeltoid, anterior portion of the deltoid in humans, superior most shoulder muscle clavotrapezius in the cat - Answer>>back of the neck on the opposite side of the sternomastoid (front of neck) below is acromiotrapezius. THINK GOING DOWN THE BACK OF THE NECK(TRAPEZIUS): "C" THEN "A" (BIG ONE ABOVE SHOULDER MUSCLES) adductor longus in cat - Answer>>the very top of the deep thigh muscles, above adductor femoris (order: longus-adductor femoris-semimembranosus) sartorius in a cat - Answer>>top of thigh, anterior half of the thigh, flattened band, large, most anterior muscle in the cat thigh, versus the human sartorius is thin and on top of the muscles,
lateral to tensor fasciae latae, on the lateral side of the thigh unlike gracilis which is on the medial side of the thigh gracilis in a cat - Answer>>medial aspect of thigh on the inner thigh (sartorius is lateral on the inner part of the thigh) they are both large muscles acromiotrapezius in cat - Answer>>on top of the huge two oval chest muscles(supraspinatus/infraspinatus, teres major), below clavotrapezius (back of neck), sandwiched between clavotrapezius and spinodeltoid, forms a "N" or "U" shape takes the place of where the trapezius muscle would be in the human, goes around to the front/abdomen side too, upper back, stops at the base of the neck (clavotrapezius goes up neck), lateral is spinodeltoid and the rest of the shoulder muscles (acromiodeltoid, clavodeltoid) and going downward the arm (biceps and triceps) spinotrapezius in cat - Answer>>most posterior of the three trapezius (cover the back) muscles below acromiotrapezius, overlaps latissimus dorsi on the front side, corresponds to the inferior portion of the human trapezius muscle, in other words because the cat doesnt have the trapezius muscle the upper back is broken into several different muscles, the spinotrapezius is at the very bottom above latissimus dorsi (lower back muscle) caudofemoralis in cat only - Answer>>Narrower, longer flap inferior/below to gluteus maximus, hip muscle, found in pelvic limb, near tail, above biceps femoris sciatic nerve in human - Answer>>runs down the posterior aspect of the thigh, inferior to biceps femoris sciatic nerve in cat - Answer>>inferior to biceps femoris vastus lateralis in a cat - Answer>>on the lateral side of the rectus femoris
semitendinosus in a cat - Answer>>posterior in a cat semimembranosus in human - Answer>>hamstring muscle, most medial -medial thigh/adductor compartment muscle -most medial, underneath semitendinosus -cat has this muscle on the anterior side semimembranosus in a cat - Answer>>anterior medial thigh, in humans it is on the posterior side, under/inferior to adductor femoris biceps femoris in human - Answer>>hamstring muscle, only hamstring muscle (includes semimembranosus, semitendinosus, and biceps femoris) on the lateral side of popliteal space. Semitendinosus and Semimembranosus is on the medial side of the popliteal space. (semitendinosus is a strip of muscle on top semimembranosus which surrounds both sides of semitendinosus) adductor compartment muscles - Answer>>-aka medial thigh (5) Muscles: -Pectineus -Adductor longus -Adductor magnus -Adductor brevis -Gracilis -adductor femoris (CAT ONLY) pectineus in human - Answer>>-medial thigh/adductor compartment muscle -most medial against pubic symphisis and vessel, the very top thigh muscle above adductor longus
adductor longus in human - Answer>>bigger, straight muscle, on the medial side of the sartorius, middle of the inner thigh adductor muscles (pectineus, adductor brevis, adductor longus, adductor magnus), medial thigh/adductor compartment muscle, under adductor brevis (order top to bottom: pectineus, adductor bevis, adductor brevis, adductor longus, adductor magnus, gracilis (medial most) adductor femoris in cat - Answer>>-medial thigh/adductor compartment muscle -takes the place of adductor brevis in the human which is in between adductors magnus and longus -in CAT ONLY, deep muscle sandwiched between adductor longus (at the top, magnus in humans) and semimembranosus (longus in humans) -Cat inner thigh: adductor longus-adductor femoris-semimembranosus vs. human inner thigh: adductor magnus-brevis-longus adductor magnus in human - Answer>>medial thigh/adductor compartment muscle HUMAN ONLY, underneath/behind adductor longus, in posterior view it is on the medial aspect of the thigh next to gracilis at the top adductor brevis in human - Answer>>medial thigh/adductor compartment muscle, sandwiched between pectineus and adductor longus, smaller muscle underneath pectineus, above adductor longus HUMAN ONLY, ORDER: pectineus, adductor brevis under adductor longus, adductor magnus under longus (seen posteriorly too) gracilis in human - Answer>>-medial thigh/adductor compartment muscle -most medial thigh muscle -reveals adductor magnus -straight muscle running all the way down to the tibia/knee joint -inside "V" of adductor longus and adductor magnus superior calf muscles - Answer>>soleus, gastrocnemius, plantaris
