PORTAGE LEARNING BIOD 152 A&P 2
MODULE 2 EXAM
Question 1
3 / 3 pts
This layer of the meninges is tightly attached to
the brain. Your Answer:
Pia- mater
Pia mater (menix)
Question 2
3 / 3 pts
The fissure separates the cerebrum from the
cerebellum. Your Answer:
The transverse fissure
Transverse
Question 3
4 / 4 pts
Describe the function of the brain
ventricles. Your Answer:
Brain ventricles ARE 4 and are found inside the brain and
filled with CSF. 2 laterals and 3rd and 4th ventricles all of
them drain in the central canal of the spinal cord and
contains CSF; their main function it is where the CSF is
made which helps to absorb impacts when the brain
faces them for any activity or movements
There are four ventricles in the interior of the brain,
chambers filled with cerebrospinal fluid which is produced
there. Once formed the CSF circulates through the ventricles
and into the subarachnoid space bathing and floating the
brain.

All the following are functions of the hypothalamus except : Maintain homeostasis Controls the pituitary gland Links the nervous and endocrine systems Correct! Relays sensory impulses to the cerebrum***** Question 5

2 / 2 pts

This ventricle is located anterior to the cerebellum. Later al Media l Third Fourth Question 6

2 / 2 pts

This region of the brain controls decision making skills. Frontal lobe Cerebellum Occipital lobe Temporal lobe

Correct Answer Question 7

0 / 2 pts

A patient is having difficulty understanding language but is still able to speak fluently. The patient’s dermatomes are intact. Which area of the brain is most likely damaged? Broca’s area Wernicke’s area Occipital lobe Parietal lobe Primary sensory cortex Question 8

1 / 2 pts

What is muscle tone and how is it maintained? Your Answer: It is manage by the sensory muscles spindles which work with the stretching of the muscles; it helps to maintain muscles contraction. It is crucial for creating reflexes help with the postures and the equilibrium Correct answer Muscle tone is the degree at which muscles remain partially contracted while at rest. Muscle tone is continuously monitored and maintained by the cerebellum to keep bones and joints in place. Question 9

2 / 2 pts

Which statement is false concerning the brainstem? The medulla portion of the brainstem continuous with the spinal cord.

Correct! Correct Answer Correct! The medulla contains reflex centers to regulate vasoconstriction. The midbrain contains the superior and inferior colliculi. The midbrain helps to regulate breathing. Question 10

0 / 2 pts

Which of the following is true concerning the cerebellum? The gray matter is internal while the white mater is external. The cerebellum works to plan body movements by relaying information spinal cord. The anterior lobe receives information from the body trunk. The vermis coordinates the trunk and shoulder movements. Question 11

2 / 2 pts

Alzheimer’s disease impacts which region(s) of the brain? Occipital lobe Frontal lobe Parietal lobe Hippocamp us All the above

Correct Answer Question 26

0 / 3 pts

Which of the following is false concerning the sympathetic nervous system? It is also called the thoracolumbar division. It is also called the craniosacral division. The primary neurotransmitter is norepinephrine. It inhibits the digestive tract. Question 27

0 / 4 pts

If you were hiking in the woods and came across a mountain lion, which division of your nervous system would have increased activity? Explain your answer. Your Answer: Correct answer The sympathetic nervous system would have increased activity as it is responsible for preparing our bodies to respond to stressful situations. Question 28

0 / 5 pts

If someone sustains an injury to the area of the spinal cord, as shown below by the blue oval, would you be more likely to see paralysis or decreased sensation? Explain your answer.

Your Answer: You would be more likely to see decreased sensation because sensory neurons enter the spinal cord posteriorly. Question 29

0 / 5 pts

One of your patients sustained a hemorrhagic CVA. You notice they have rigid movements when moving their arms. They also have difficulty forming a plan to move their body. What area of the brain is most likely impacted? Explain your reasoning. Your Answer: Correct answer The basal ganglia is responsible for executing a motor plan and to slow and control fine movements (creating the rigid movements). Apraxia, or impaired motor planning. Apraxia results in rigid movements and difficulty executing a motor plan.
