Flashcards in Overview, Blood Supply, & Spinal Cord--Exam I (Practicum) Deck (21):
1

What is Gray Matter?

Areas of neuronal cell bodies and synapses

2

What are the three parts to the brainstem?

Midbrain, Pons, Medulla

3

What is white matter?

Areas mostly composed of myelinated axons

4

What are the 5 lobes of the cerebrum?

1. Frontal 2. Parietal 3.Temporal 4. Occipital 5. Insular

5

Where is the corpus callosum? What is its function?

It connects the two hemispheres, all White Matter. Looks like a slide on top of limbic system under hemispheres

6

Where are the optic radiations? Fxn?

Look in posterior of brain, from a inferior view. White matter that relays visual info to the primary visual cortex

7

Where is the Internal Capsule? Fxn?

White matter fibers that extend from the brian down. Look for "greater then" sign in transverse section.

8

What divides the frontal lobe and the parietal lobe?

The central sulcus

9

What divides the temporal lobe from both the frontal lobe and the parietal lobe?

The Lateral Sulcus

10

Which lobe do you find if you wedge the lateral sulcus open?

The Insular Lobe (The Insula)

11

What is the area that is receptive to language? About where do I find it?

Wernicke's Area, mostly temporal lobe, some of parietal lobe

12

Which area takes part in forming out going speech. Where might I find it?

Bro-Ca's area. In the frontal lobe

13

What is the tissue that separates the two hemispheres?

The Great Longitudinal Fissure

14

What is the function of the pre central gyrus?

Primary Motor Cortex

15

What is the function of the post central gyrus?

Primary SomatoSensory Cortex

16

What separates the Parietal and Occipital lobes?

Parieto-Occipital Sulcus

17

What separates the occipital lobe into superior and inferior?

Cal-Car-ine Sulcus

18

What separates the limbic lobe/cingulate from the frontal/parietal/and occipital lobes?

The cingulate gyrus

19

What are the three structures of the Diencephalon? Which ventricle do they surround?

The Thalamus, The Hypothalamus, and the EpiThalamus (PINE-EEL gland). They surround the 3rd ventricle

20

What are the five Basal Ganglia?

1. Caudate Nucleus 2. Putamen 3. Globus Pallidus 4. SubThalmic Nucleus 5. Substantia Nigra

21

What are the 8 players in the Limbic system?

1.Frontal Lobe 2. Temporal Lobe 3. Cingulate Gyrus 4. Thalamus 5.Hypothalamus 6. Hippocampus 7. Amygdala 8. Olfactory System
