1

Stalk like part of the
brain ; located in the
posterior cranial fossa

Brainstem

2

The brain stem consists of:

Midbrain
Pons
Medulla oblongata

3

T or F:

The midbrain is the shortest part of the brainstem

TRUE

4

Contains the nuclei of (CN?)

Oculomotor and Trochlear nerves

5

The midbrain's centers are associated with

auditory, visual and pupillary reflexes

6

PonsForms the floorof therostralpart of the 4thventricle

Pons

7

Contains nuclei related to (CN?)

Trigeminal, Abducent,Facialand Vestibulocochlearnerves

8

The pons' centers are associated with

mastication, eye movements, facial expression, blinking, salivation, equilibrium and audition

9

Forms the caudal floorof the 4th ventricle

Medulla oblongata

10

Contains nuclei related to (CN?)

Glossopharyngeal, Vagus, Accessoryand Hypoglossal nerves

11

Medulla oblongata's centers are associated with

deglutition, coughing, vomiting, salivation, tongue movements, respiration and circulation

12

2 parts of the the floor of the 4th ventricle

Pontine and medullary

13

MEDULLA OBLONGATA
On either side of the posterior median sulcus is the

Gracile tubercle

14

MEDULLA OBLONGATA
Lateral to each gracile tubercle is the

Cuneate tubercle

15

It receives input from all parts of nervous system and in turn, exerts widespread influence on CNS function

Reticular formation

16

T or F:

The brainstem is important in localizing lesions or injuries

TRUE

17

Separated by the cerebral aqueduct and periaqueductal gray matter

Superior Colliculi

18

The cerebral peduncle is composed of

tegmentum, substancia nigra and cerebral crus

19

Separated by cerebral aqueduct and periaqueductal gray matter

Inferior colliculi

20

The decussation of the trochlear nerve is in the

upper pons

21

The trigeminal nerve attachment

middle pons

22

This posturing signifies a higher level of brainstem involvement

decorticate

23

T or F:
In comatose patients-
If decorticate to decerebrate positioning of the patient may become life threatening because of the vital respiratory and cardiovascular centers in the medulla

True
