Flashcards in Broadmann Area Deck (12):
1

Voluntary motor INITIATION esp. in the distal extremities & facial musculature

4

2

ONLY area to contain giant pyramidal (Betz) cells.

4

3

Well developed projection laminae V & VI

4

4

Corticospinal fibers orginate here along with sending projections to the basal ganglia, pontine nuclei, reticular formations, red nucleus, superior colliculus, vestibular & inferior olivary nuclei as well as all brainstem nuclei

4

5

Located in the post central gyrus of the parietal lobe

1,2,3

6

Best known as the somesthetic cortex (body sensing)

1,2,3

7

Pain, thermal, deep touch, light touch, vibratory & kinesthetic input is received & integrated into conscious sensation in this gyrus

1,2,3

8

Great somesthetic cortex is also subtly contributing pyramidal fibers to the voluntary motor initiation pathways

1,2,3

9

Confinded to the precentral gyrus of the frontal lobe

4

10

These 2 areas are located in front of 4. Sometimes called the "premotor" regions

6 & 8

11

Motor initiation centers contribting fibers Directly & Indirectly to the pyramidal system

6 & 8

12

Influence on the proximal portions of our extremities
