Answer 4

Anaxonic, Bipolar, Unipolar & Multipolar

Question 5

Anaxonic

Answer 5

Found in brain & sense organs

Question 6

Bipolar Neurons

Answer 6

Found in special sensory organs

Question 7

Unipolar

Answer 7

found in sensory neurons of PNS

Question 8

Mulipolar

Answer 8

Common in CNS

Includes all skeletal muscle motor neurons

Question 9

sensory neurons

Answer 9

Carry nerve impulses from peripheral body parts into the brain or spinal cord

Question 10

interneurons

Answer 10

transmit impulses from one part of the brain or spinal cord to another

Question 11

Motor neurons

Answer 11

Carry impulses out of the brain or spinal cord to muscles or glands

Question 12

synapse

Answer 12

Area where a neuron communicates with another cell

Question 13

Meninges

Answer 13

membrane is coverings of the brain and spinal cord

Question 14

spinal cord

Answer 14

a nerve column that extends from the brain. It is composed of three segments. It provides the communication system between the brain and other body parts

Question 15

The Cerebrum

Answer 15

5 lobes: Frontal, parietal, temporal, occipital, insula

2 layer: outer - gray matter
inner - white matter

Question 16

functions of the cerebrum

Answer 16

interpret sensory impulses, initiates involuntary muscular movements, stores information, determines intelligence and personality

Question 17

Ventricles

Answer 17

• Interconnected cavities filled w/ cerebrospinal fluid

LOCATED: 1st & 2nd extend into the cerebral hemisphere & occupy portions pf the frontal temporal & occipital lobes. 3rd is at the midline of the brain. 4th is at the brainstem

Question 18

Brainstem

Answer 18

• Connects the cerebrum to the spinal cord

- It contains the diencephalon, midbrain, pons & medilla oblongata

Question 19

Pons

Answer 19

located on the underside of the brainstem, it transmits impulses between cerebrum and other nervous system

Question 20

mid brain

Answer 20

located between the diencephalon and the pons

-reflex centers associated w eye & head movement

Question 21

cerebellum

Answer 21

mass under our submittal lobes, coordination a skeletle muscle movements

Question 22

diencephalon

Answer 22

2 parts:

1: Thalamus - base of the cerebrum / is the central relay station
2: hypothalamus: connected to the cerebral cortex and thalamus. Maintains homeostasis

Question 23

reticular formation

Answer 23

extends the spinal cord to the diencephalon

filters incoming sensory impulses and arouses wakefulness

Question 24

Medela oblongata

Answer 24

continuation of the spinal cord from the ponds
