Review
Fluid-filled chambers that are continuous to each other and the central canal of the spinal cord.
The ventricles
forms superior part of brain
Cerebral hemispheres
•Large part of emotional or affective brain
Limbic System
•Cushion of fat and network of veins in space between vertebrae and spinal dura mater
•Epidural space
Gyri
Ridges
The inside has this fluid found within the brain.
Cerebrospinal fluid
Gray Matter
short, nonmyelinated neurons and cell bodies
involved in speech production
Broca’s area
Processes input from cortex, brain stem, and sensory receptors to provide precise, coordinated movements of skeletal muscles
Cerebellum
Sulci
Shallow grooves
This type of neuroglia cells line and help circulate the fluid
Ependymal cells
myelinated and nonmyelinated axons
White matter
•involved in understanding spoken and written words
Wernicke’s area
Schwann cells are functionally similar to
oligodendrocytes
Fissures
Deep grooves
An individual who could trace a picture of a bicycle with his or her finger but could not recognize it as a bicycle is most likely to have sustained damage to the
visual association area
large, C-shaped chambers located deep in each hemisphere
Paired lateral ventricles
•consolidated memories are not lost, but new inputs are not associated with old one
Anterograde amnesia
The area of the cortex that is responsible for sensing a full bladder and the feeling that your lungs will burst when you hold your breath too long is the
visceral sensory area
executive suite” of brain
Cerebral cortex
What does the central nervous system use to determine the strength of a stimulus?
frequency of action potentials
Name the four regions of the brain
1.Cerebral Hemispheres
2.Diencephalon
3.Brain Stem
4.Cerebellum
meninges consists of three layers
layers (from external to internal): dura mater, arachnoid mater, and pia mater
Saltatory conduction is made possible by ________.
the myelin sheath
Diencephalon consist of what three paired gray matter structures
•Thalamus
•Hypothalamus
•Epithalamus
