Study Notes
Eye Innervation
- The main reason for the eye being highly innervated is to ensure precise and complex movement of the eyes.
Nervous System and Ocular Structures
- The sensory information that travels towards the brain from ocular structures is visual and touch information.
- The branch of the nervous system responsible for delivering sensory information from ocular structures to the brain is the sensory branch.
- Cranial nerve II (Optic Nerve) delivers visual information to the brain.
- Cranial nerve V (Trigeminal Nerve) delivers touch information to the brain from the ocular structures.
Nervous System Structure
- The author compares the structure of the nervous system to a complex network of roads and highways.
- The autonomic nervous system is not mentioned in the context of ocular innervation.
Neuron Function
- The part of a neuron primarily responsible for initiating and relaying electrical impulses is the axon hillock.
- The main function of a Schwann cell in nervous tissue is to provide support and insulation to neurons.
- Afferent neurons are primarily involved in sensation of touch, vibration, and pain.
- The main function of the axon hillock in a neuron is to integrate and amplify excitatory and inhibitory signals.
Neuronal Communication
- Dendrites are responsible for communicating with other cells via specialized connections called synapses.
