Gray and white matter
What are nerve fibers that connect one part of the brain to another?
White Matter
(PP slide 21)
How many different lobes are in the Cerebrum?
Four Lobes
(PP slide 29)
What is the main function of the primary motor cortex?
Motor control
(PP slide 54)
Where does the Corticospinal track begin?
Motor Cortex
(PP slide 24)
Where does the Corticobulbar tract begin?
The motor cortex
(Page 23)
Why is gray matter gray?
The cells appear gray in the absence of myelin; thus, they are also called gray matter (page 15)
How many different hemispheres are in the Cerebrum?
Two
(PP slide 29)
What is the main job of the Broca’s area?
Speech production
(PP slide 54)
Where does the Corticospinal track end?
Spinal cord
(PP slide 24)
Where does the Corticobulbar end?
In the bulbar area (medulla and adjacent brainstem areas.)
(Page 23)
What is white matter in the brain responsible for?
Allows the exchange of information and communication between different areas of your brain (page 15)
What is a Gyrus?
the hills on the surface of the Cerebrum
(PP slide 31)
What are the functions of the Hypothalamus?
Regulation of body temperature, water and food intake, sugar metabolism, sexual behavior, and emotional state. (PP slide 64)
What is the corticospinal tract?
A motor pathway of the spinal cord
(page 61)
What is the main purpose of the Corticobulbar?
To control the muscles of the face, head, and neck (page 23)
Why is white matter white?
It is white because of the white appearance of the myelin lipid (fat-like) substance surrounding many of the axons. (page 15)
What is a Sulcus?
the valleys in the Cerebrum
(PP slide 31)
What is one of the functions of the Basial Ganglia?
Regulation of muscle tone
(PP slide 61)
What are the two corticospinal tracts?
The lateral corticospinal tract and the anterior corticospinal tract
(page 61)
The Corticobulbar plays an important part in?
Motor speech processes
(page 73)
What makes up gray matter?
Neurons and Glial cells
(PP slide 21)
What forms a boundary between the frontal and the parietal lobes?
Central Sulcus
(PP slide 30)
What is the main function of the midbrain?
Controls reflexes and reflexive eye and head movements in response to external stimuli (PP slide 68)
The corticospinal tract contains?
Axons of the pyramidal cells
(page 61)
The Corticobulbar passes through the?
Midbrain, Pons, and Medulla (PP page 24)
