Study Notes
Neuroanatomy Key Concepts
- Arbor Vitae: Refers to the distinctive tree-like pattern of white matter found in the cerebellum, essential for its function.
- Cerebellar Peduncles: Paired fiber tracts that serve as the connection between the cerebellum and the brain stem, playing a critical role in motor control and coordination.
- Folia: The pleatlike convolutions of the cerebellum, which increase the surface area for neuronal processing.
Cerebral Cortex Areas
- Primary Auditory Cortex: Situated in the temporal lobe; responsible for processing auditory information.
- Primary Olfactory Cortex: Located in the temporal lobe; involved in the processing of smell sensations.
- Primary Somatosensory Cortex: Found in the parietal lobe; integrates sensory information from the body, including touch, temperature, and pain.
- Primary Visual Cortex: Located on the occipital lobe; dedicated to processing visual stimuli.
Spinal Cord Structure
- Gray Matter: Found inside the spinal cord, containing neuronal cell bodies, whereas white matter surrounds it, consisting primarily of myelinated axons.
- Ventral Motor Root: Part of the spinal cord's anatomy responsible for sending motor signals from the spinal cord to the muscles.
- Dorsal Root Ganglia: Contains the cell bodies of sensory neurons in the spinal nerves, essential for relaying sensory messages to the central nervous system.
