Definition
| organ that is lateral to the brainstem. Has hemispheres (called minor hemispheres). Called cerebellar hemispheres. |
|
|
Term
|
Definition

Term
| function of the cerebellum |
|
Definition
it is concerened with motor functions.
able to compare the goal of the movement and the current status of the movement. By comparing the goals of the cerebellum it can make adjustments in order to reach the goal. |

Term
| when is a spinal nerve formed? |
|
Definition
| when the dorsal and the ventral root meet up together. this in turn gives us a mixed nerve. |
|
|
Term
| spinal nerve outside of vertebra |
|
Definition
splits after awhile, splits into ramus/rame
posterior ramus- serves the back of the body. Bothh sensory and motor fibers
anterior ramus- serves the front of the body. both sensory and motor fibers.
ramus is associated with mixed nerve |
