- A test organism develops a genetic mutation that causes neurons to develop without synaptic knobs. How will this impact neuronal function?
No neurotransmitters will be released into the synapse to signal the postsynaptic neuron, as the synaptic knob is where they are stored.
- Which of the following bone shape is stated with an incorrect example?
flat bone- thigh bone
- If a red blood cell is placed in a hypotonic solution, what will happen to the cell?
The cell will swell and may eventually burst.
- The increase in the number of motor units activated as a result of more intense stimulation is called what?
recruitment
- Sweat cools the body by what process?
evaporation
- Osteoclasts are bone-resorbing cells, whereas osteoblasts are bone-forming cells. True or False?
true
- Humans require vitamins in their diets because these nutrients act as what?
act as coenzymes
- The major components of the cell membrane are what?
lipids and proteins
- The function of the association area in the frontal lobe is what?
higher intellectual processes, such as reasoning and judgment.
- Which of the following best describes the reaction NaNO3 + HCl → HNO3 + NaCl?
exchange reaction
- What is the relationship of osmotic pressure to the number of solute particles in a solution?
The greater the number of impermeant solute particles, the greater the osmotic pressure.
- If the area of the cerebral hemisphere corresponding to Broca's area is damaged, what is the consequence?
motor control of the muscles associated with speech is lost.
- A mutation can cause disease if what occurs?
the DNA sequence changes so that one amino acid is substituted for another in a way that affects the encoded protein's functioning.
- If a person contracted meningitis (an inflammation of the meninges due to infection), which specific nervous structures would be inflamed and swollen?
The pia mater, arachnoid mater, and dura mater
- Transmitting an impulse from one neuron to another involves what process?
impulse stimulating a presynaptic axon to release a neurotransmitter into a synaptic cleft.
- Describe the role of the epiphyseal plate in long bone growth and what can be determined by examining it in a radiograph.
The epiphyseal plate, also known as the growth plate, is a hyaline cartilage plate located at the ends of long bones in children and adolescents. It is the area where bone growth in length occurs. Chondrocytes within the epiphyseal plate proliferate and produce new cartilage matrix, which is then replaced by bone tissue through endochondral ossification. Examining a radiograph of a long bone allows one to determine if the epiphyseal plate is still present, indicating that the bone is still growing. The absence of the epiphyseal plate, or the presence of an epiphyseal line (its remnant after growth has ceased), indicates that the bone has reached its full length and growth has stopped.
- Explain how Golgi tendon organs respond to muscle tension and what their function is.
Golgi tendon organs (GTOs) are sensory receptors located within tendons, near the junction of the muscle and tendon. They are stimulated by increased tension within the tendon, which occurs when a muscle contracts or is stretched. When tension increases, the GTOs send signals to the spinal
