Study Notes
Cranial Nerves and the Brain
- The frontal lobe is responsible for generating motor commands.
- The hypothalamus coordinates homeostasis.
- The midbrain is the major input to the cerebellum.
- The anterior horn of the spinal cord contains motor neurons controlling skeletal muscles.
- Brodmann's areas map different regions of the cerebral cortex to specific functions.
Blood Vessels and the Brain
- The internal carotid artery supplies the brain with oxygenated blood.
- The pia mater surrounds and supports the sinuses that drain cerebrospinal fluid (CSF).
- Ependymal cells filter blood to produce CSF at the choroid plexus.
- The third ventricle is located within the diencephalon.
- A stroke is caused by a disruption of blood flow to the brain.
Ganglia and Nerves
- Autonomic ganglia contain neurons controlling body homeostasis.
- A bundle of axons within a nerve is called a fascicle.
- The somatosensory cortex (largest region) represents the lips.
- The primary motor cortex initiates movement by directly connecting to motor neurons.
- The tectospinal tract incorporates equilibrium sensations with motor commands for posture and movement.
Spinal Cord
- The ventral horn contains motor neurons innervating skeletal muscles.
- A withdrawal reflex protects the foot when a painful stimulus is sensed.
- The homunculus is the topographical representation of sensory input to the somatosensory cortex.
