1
Q

Three main divisions of Brainstem

A

Midbrain, pons, medulla

2
Q

Cranial nerve 1

A

enters into anterior fossa and carries olfactory info

3
Q

Cranial nerve 2

A

passes from orbit and into middle cranial fossa, carries visual information

4
Q

Cranial nerves 3, 4, 5, 6

A

emerge from brainstem within posterior cranial fossa, travel forward to reach the middle cranial fossa and through foramen in middle cranial fossa in order to exit cranial cavity

5
Q

cranial nerves 7, 8,9,10,11, and 12

A

emerge from brainstem in posterior cranial fossa, course for a short distance then exit cranial cavity via foramen in posterior cranial cavity

6
Q

Brainstem levels, rostral to caudal

A

Rostral midbrain, pons,rostral medulla,caudal medulla

7
Q

Brainstem: cross section regions

A

Tectum, Tegmentum, Basal Portion

8
Q

Tectum

A

dorsal, posterior to ventricular spaces

9
Q

Tegmentum

A

mid-region anterior to ventricular spaces (reticular formation found here)

10
Q

Basal Portion

A

ventral region

11
Q

Reticular formation

A

complex neural network in core of medulla pons and midbrain, regulates neural activity throughout the CNS. Helps regulate: resporatory and cardio functions, altertness, attention motivation, and motor movement
