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.
