Definitions I need to know - Year 1 Semester 2

proprioception

the body's ability to sense its position, movement, and orientation in space, allowing for coordination and balance.

somatosensory

system responsible for processing sensory information from the body

skin

pressure receptors that detect touch, temperature, and pain.

joint

joint receptors detect changes in joint position and movement

muscle

muscle spindles that detect changes in muscle length and provide information about body position and movement.

cerebellum

thalamus

processes the information and filters out and edits out what doesn’t need our attention right now by inhibiting that information from reaching the cortex

optic nerve

the nerve that transmits visual information from the retina to the brain.

optic chiasm

The point where the optic nerves from each eye cross. This structure is crucial for binocular vision and the processing of visual information.

golgi tendon organ

a sensory receptor located at the junction of muscles and tendons that detects changes in muscle tension and promotes relaxation to prevent injury.

afferent

nerves that carry sensory information to the central nervous system.

dermatones

Regions of the body that correspond to specific spinal nerves

peripheral

nervous system that connects the central nervous system to limbs and organs, including sensory and motor pathways.

white matter

made from myelinated axons in vertebrae

grey matter

made from synapses in vertebrae

cerebral cortex

dorsal columns medial lemniscus

primary sensory cortex

association cortex

Lateral spinothalamic

homunculus
