Ch13. Sensory & Motor Pathways

A ____ is the route a signal takes from your skin (or body) to your brain.

pathway

Steps in the pathway:

Sensory Receptor gets stimulated (e.g. you touch something) ➡Signal travels through afferent neurons➡Arrives at spinal cord → thalamus → brain

____ pathways send signals to the brain

Sensory

___ pathways send signals from the brain to the muscles.

Motor

____ carries information to the brain (sensory)

Afferent

__ carries information from the brain (motor).

Efferent

What does the spinothalamic pathway carry?

Pain and temperature sensations to the brain

What does the posterior column pathway carry?

Fine touch, vibration, and proprioception.

What does the spinocerebellar pathway carry

: Proprioception information to the cerebellum for coordination.

What is proprioception?

The sense of body position and movement.

What does the corticospinal pathway control?

What does the corticospinal pathway control?

What is the role of the cerebellum in motor control?

To coordinate and fine-tune movements using proprioceptive input.

What does the thalamus do in sensory pathways?

Acts as a relay station that sends sensory information to the correct part of the brain.
