Regulation of skeletal muscle contractions
What is a fissure?
Deep grooves that subdivide hemispheres
What is a gyrus?
A fold in the cerebral cortex that increases the surface area
What is a sulcus?
A shallow depression in the cerebral cortex that separates adjacent gyri
What is the second largest structure in the brain?
What is the function of the cerebellum?
Coordination and modulation of motor commands from cerebral cortex
What is the Diencephalon?
Structural and functional link between cerebral hemispheres and rest of CNS
Describe the diencephalon.
Almost completely covered by cerebrum
Between cerebral hemispheres and above the brainstem
Connected to midbrain below
Surrounds 3rd ventricle
Mainly gray matter
What are the major parts of the Diencephalon?
Describe the Epithalamus.
very small region on upper, posterior part of thalamus; most dorsal part of diencephalon; forms roof of third ventricle
Describe the Thalamus.
Relay and processing centers for sensory information; Forms walls of third ventricle, bulges in from each side
Describe the location and structure of the hypothalamus.
forms lower walls and floor of third ventricle, below thalamus
What are the functions of the hypothalamus.
What are some secondary structures of the Diencephalon?
What is the function of the mammillary bodies?
Olfactory relay stations in the olfactory pathways.
