Question 1 3 / 3 pts This is the most superficial layer of the brain meninges. Your Answer: pia mater Dura mater (menix) Question 2 3 / 3 pts The _______ fissure separates the right and left cerebral hemispheres. Your Answer: median longitudial Median longitudinal Question 3 4 / 4 pts What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular level. Your Answer: prevents most particles from entering the central nervous system. It keeps the brain separated from the spinal cord for blood circulation The blood-brain barrier is a diffusion barrier which prevents most particles from entering the central nervous system tissue, keeping the brain and spinal cord separate from general blood circulation. The blood-brain barrier is formed by the relatively impermeable brain capillaries, due to the glial cells astrocytes. Maintenance of the blood-brain-barrier is important to provide a stable chemical environment for the nervous system. Question 4 2 / 2 pts All the following are functions of the hypothalamus except: Maintain homeostasis Controls the pituitary gland Describe how memories are stored and retrieved in the brain. Include a specific brain region. Your Answer: (cerebral hemispheres) The hippocampus is a memory center and helps with memory storage Memories are not stored in one specific area within the brain but instead are stored throughout the cerebral hemispheres. The hippocampus acts as a memory center to help with memory storage and retrieval. The involvement of the limbic system explains why emotionally charged events result in our most vivid memories. Question 9 2 / 2 pts Which statement is false concerning the brainstem? The medulla portion of the brainstem continuous with the spinal cord. The medulla contains reflex centers to regulate vasoconstriction. The midbrain contains the superior and inferior colliculi. Correct! The midbrain helps to regulate breathing. Question 10 0 / 2 pts Which of the following is false concerning the cerebellum? The gray matter is external while the white mater is internal.
