Module 5 (NERVOUS TISSUE)

Question 1

Most complex system in the body histologically and physiologically.

Answer 1

NERVOUS TISSUE

Question 2

Formed by a network of many billion nerve cells (neurons), assisted by many more glial cells.

Answer 2

NERVOUS TISSUE

Question 3

DIVISION OF NERVOUS SYSTEM

Answer 3

CENTRAL NERVOUS SYSTEM
PERIPHERAL NERVOUS SYSTEM

Question 4

consisting of the brain and spinal cord

Answer 4

CENTRAL NERVOUS SYSTEM

Question 5

composed of cranial, spinal, and peripheral nerves conducting impulses to and from the CNS (motor and sensory nerves respectively) ang ganglia which are small groups of nerve cells outside the CNS.

Answer 5

PERIPHERAL NERVOUS SYSTEM

Question 6

aka nerve cells

Answer 6

NEURONS

Question 7

Functional unit in both CNS and PNS

Answer 7

NEURONS

Question 8

Four parts of Neurons

Answer 8

Cell body / perikaryon
Dendrites
Axon
Terminal Arborization

Question 9

synthetic or trophic center for the entire nerve cell and is receptive to stimuli

Answer 9

Cell body / perikaryon

Question 10

many elongated processes specialized to receive stimuli from the environment, sensory epithelial cells, or other neurons

Answer 10

Dendrites

Question 11

a single process specialized in generating and conducting nerve impulses to other cells (nerve, muscle and gland cells). It may also receive information that mainly modifies the transmission of action potentials to those neurons

Answer 11

Axon

Question 12

CLASSIFICATION OF NEURONS

Answer 12

MULTIPOLAR NEURONS
BIPOLAR NEURONS
UNIPOLAR or PSEUDOUNIPOLAR NEURONS

Question 12

branched distal portion of the axon. Each branch terminatees on the next cell

Answer 12

Terminal Arborization

Question 13

which have one axon and two or many dendrites

Answer 13

MULTIPOLAR NEURONS

Question 14

one dendrite and one axon

Answer 14

BIPOLAR NEURONS

Question 15

which have a single process that bifurcates close to the perikaryon, with the longer branch extending to a peripheral ending and the other toward CNS.

Answer 15

UNIPOLAR or PSEUDOUNIPOLAR NEURONS

Question 16

most neurons are ?

Answer 16

MULTIPOLAR

Question 17

neurons are found in retina, olfactory mucosa, cochlear /9inner ear) and vestibular ganglia, which they serve as senses of sight, smell, and balance respectively.

Answer 17

BIPOLAR neurons

Question 18

neurons are found in the spina ganglia and most in cranial ganglia.

Answer 18

PSEUDOUNIPOLAR neurons

Question 19

Types of Glial Cells

Answer 19

Oligodendrocyte
Neurolemmocyte
Astrocyte

Question 21

Neurolemmocyte LOCATION and FUNCTION

Answer 21

Peripheral nerves

Myelin production, electric insulation

Question 22

Astrocyte LOCATION and FUNCTION

Answer 22

CNS

CNS

Lining cavities of CNS

Question 24

Principal structures of CNS

Answer 24

CEREBRUM
CEREBELLUM
SPINAL CORD

Question 25

IT has virtually no connective tissue and is therefore a relatively soft, gel-like organ

Answer 25

CENTRAL NERVOUS SYSTEM
