This layer of the meninges is tightly attached to the brain.(ANS- Pia mater (menix)
The _______ fissure separates the right and left cerebral hemispheres.(ANS- Median longitudinal
What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular level.(ANS- 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.
All the following are functions of the hypothalamus except:
- Maintain homeostasis
- Controls the pituitary gland
- Links the nervous and endocrine systems
- Relays sensory impulses to the cerebrum

Describe how memories are stored and retrieved in the brain. Include a specific brain region.(ANS- 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
