21
Q

Anterior midbrain contains a pair of large tracts called the

A

Cerebral peduncles

22
Q

Cerebral peduncles function

A

Contain axons of motor neurons that conduct nerve impulses from the cerebrum to the spinal cord, medulla, and pons

23
Q

Loss of these neurons are associated with Parkinson’s disease?

A

Substantia nigra ( large and darkly pigmented)

24
Q

The red nuclei of the mud brain form synapses with axons from the cerebellum and cerebral cortex which function with the cerebellum to coordinate

A

Muscular movements

25
Q

Cranial nerves Associated with the midbrain

A

Oculomotor

Trochlear

26
Q

Several reflex arcs pass thru this structure involved tracking and scanning movements of the eye, head, and neck due to visual stimuli
(Midbrain)

A

Superior colliculi

27
Q

Reflex center for startle reflex, sudden movements of the head and body that occur when surprised by a loud noise
Relay auditory pathways to the thalamus

A

Inferior colliculi

28
Q

Ascending part of the reticular formation in the midbrain

A

Reticular activating system (RAS)

29
Q

RAS is involved in

A
