Motor 1

Question 1

anterior to the central sulcus

Answer 1

motor

Question 2

posterior to the central sulcus

Answer 2

sensory

Question 3

location in the brain of the feet

Answer 3

in the middle

Question 4

lower motor neurons (LMN)

Answer 4

found in the ventral horn of the spinal cord and in cranial nerve nuclei in the brain stem

Question 5

motor unit

Answer 5

a group of muscle fibers that are all innervated by a single motor neuron

Question 6

Lateral corticospinal

Answer 6

cross over in pyramids of medulla

nerve impulses to skeletal muscles -> distal parts of limbs

Lateral = Limbs

Question 7

ventral (anterior) corticospinal

Answer 7

cross over at the spinal cord level

nerve impulses to skeletal muscles -> trunk and proximal limbs

Anterior = Axial

Question 8

CORTICOBULBAR PATHWAY

Answer 8

control of skeletal muscles in the head

Corticobulbar = Cranial nerves

Question 9

role of cerebellum

Answer 9

movement

Question 10

basal ganglia

Answer 10

fine tunes movement

Question 11

final common pathway

Answer 11

LMNs

Question 12

Vestibulospinal tract

Answer 12

Ears – head movements

Question 13

Reticulospinal tract

Answer 13

Postural stability

Question 14

Rubrospinal tract

Answer 14

Red nucleus

*Precise upper limb movement!

Question 15

Tectospinal tract

Answer 15

eyes
