1

What is the frontal lobe responsible for?

Primary motor activity, behavior, speech production, emotional changes (flatness)-- relating to behavior

2

What is the parietal lobe responsible for?

Primary somatosensory and proprioception; association of somatosensory, vision, audition; formation of egocentric space and sense of self.

3

What is the temporal lobe responsible for?

Audition, olfaction, memory

4

What is the occipital lobe responsible for?

Vision

5

What is the end of the spinal cord called?

Conus medullaris

6

Which part of the spinal cord are the sensory nerve tracts?

Dorsal horns

7

Which part of the spinal cord are the motor neurons?

Ventral horns

8

What 3 structures make up the brainstem?

Midbrain, Pons, and Medulla oblongata

9

What is the medulla oblongata responsible for?

Respiration, cardiac center, vasomotor center, reflex centers for vomiting, swallowing, coughing, sneezing

10

What are the corticospinal tracts?

Pyramids

11

Where are the pyramids?

Medulla oblongata

12

What is the decussation of the pyramids?

Where motor fibers from the left hemisphere cross to the right and vice versa.

13

What CN nuclei are in the medulla oblongata?

CN IX, X, XI, XII (glossopharyngeal, vagus, accessory, and hypoglossal)

14

What does the name "pons" mean?

Bridge

15

What does the pons contain?

Fiber tracts connecting the medulla and cerebellum with upper portions of the brain

16

What is the pons responsible for?

Respiratory centers that work with the medulla

17

What CN nuclei are in the pons?

CN V (motor), VI, VII, and part of VIII (trigeminal, Abducens, facial, vestibulocochlear)

18

Where is the substantia nigra located?

midbrain

19

What does the midbrain contain?

cerebral pundlecles; connecting tracts from pons to cerebellum

20

What is the Substantia Nigra?

Dopamine producing regions

21

What is the Corpora quadrigemina?

The masses that make up the superior and inferior colliculi.

22

where is the Corpora quadrigemina?

Midbrain

23

What CN nuclei are in the midbrain?

CN III, IV, V (sensory) (oculomotor, trochlear, trigeminal)

24

What ventricular structure passes through the midbrain?

Cerebral aqueduct

25

What ventricular structure is located in the medulla?

Part of the 4th ventricle

26

What is the cerebellum responsible for?

balance/posture, learning of motions, cognitive functions, motor coordination

27

What will damage to the cerebellum result in?

lack of coordination in gait, speech, etc

28

What are the hemispheres of the cerebrum connected by?

The corpus callosum

29

What is the cerebral cortex responsible for?

sensorimotor integration and perceptive qualities of our experiences

30

What is a gyrus?

convolution of cortex

31

what is a sulcus?

gap between the gyri

32

What is the longitudinal fissure?

divides the brain into the right and left hemispheres

33

What is the Lateral (Sylvian) sulcus?

separates temporal lobes from the frontal lobes

34

What is the central sulcus?

Separates frontal lobe from the parietal lobes

35

Where is the sensory homunculus represented?

postcentral gyrus of the parietal lobe

36

Where is the motor homonculus represented?

on the pre central gyrus of the frontal lobe

37

What is received by the thalamus?

all sensory stimuli, except olfactory

38

What happens to the sensory stimuli from the thalamus?

integrated and relayed through thalamocortical radiations to specific cortical areas

39

What comprises the walls and floors of the third ventricle?

The hypothalamus

40

What is the hypothalamus chief region for?

integration of the autonomic nervous system

41

What does the hypothalamus do?

Regulates water balance, body temperature, and thirst

42

What antidiuretic hormone is produced in the hypothalamus?

Oxytocin
