Nervous System

Front 1

Nervous System

Back 1

is responsible for regulating and coordinating the activities of all the other systems of the body. It enables a person to speak, listen with understanding, comprehend what is going on around, solve problems, interact intelligently, and be creative.

Front 2

Divisions of the Nervous System

Back 2

Central Nervous System or CNS

Peripheral Nervous System or PNS

Front 3

Central Nervous System

or CNS

Back 3

it is composed of the brain and the spinal cord. It is responsible for issuing nerve impulses and analyzing sensory data.

Front 4

Peripheral Nervous System or PNS

Back 4

includes nerves of the sensory organs. It carries all the messages sent between the central nervous system and the rest of the body. It consists of 12 pairs of the cranial nerves that originate in the brain, plus 31 pairs of spinal nerves of the spinal cord.

Front 5

Nerves Cell or Neuron

Back 5

is the basic unit of the nervous system.

Front 6

Structures of a Neuron

Back 6

Cell body
Dendrites

Axon

Synaptic Terminal

Myelin Sheath

Front 7

Cell Body

Back 7

of a neuron contains the nucleus and the most of the neuron's organelles

Front 8

Dendrites

Back 8

are the numerous, short, and highly branched extensions of the neurons that receive nerve impulses and conduct them toward the cell body.

Front 9

Axon

Back 9

is the long extension of the neuron. It carries a nerve impulses away from the cell body to another neuron or to a muscle or gland.

Front 10

Synaptic Terminal

Back 10

is the end part of a neuron.

Front 11

Myelin Sheath

Back 11

speeds up the conduction of impulses along the axon.

Front 12

Parts of the Central Nervous System

Back 12

Brain

Spinal Cord

Front 13

Brain

Back 13

it is the master control center of the nervous system. It is about 1.4 kg. responsible for issuing nerve impulses, processing nerve impulses data and engaging in the high order thought process.

Front 14

3 Parts of the Brain

Back 14

Cerebrum

Cerebellum

Brain Stem

Front 15

Cerebrum

Back 15

- it is a large mass of whole gray neutral fiber in upper cranium.

Front 16

Cerebrum

Back 16

- it is responsible for the higher thought processes such as memory, judgement and reason

Front 17

Four Division of the Cerebrum

Back 17

Frontal Lobe

Occipital Lobe

Parietal Lobe

Temporal Lobe

Front 18

Frontal Lobe

Back 18

It is located behind the frontal bone. It contains higher thought processing centers of memory, reasoning and associative conceptualizing. It is responsible for voluntary motor coordination.

Front 19

Occipital Lobe

Back 19

- It is located just in front of the occipital bone

Front 20

Occipital Lobe

Back 20

- it contains the centers responsible for sight

Front 21

Parietal Lobe

Back 21

- located in upper, middle part of the brain next to the parietal bones.- It houses the control centers for processing impulses related to the sense of touch. Temperature, texture, size, shape, and weight are analyzed and processed here.

Front 22

Temporal Lobe

Back 22

Located on each side of each hemisphere of the brain, next to the temporal bone, and houses areas for the processing and correlation of the auditory (hearing) and olfactory (smell) senses

Front 23

Cerebellum

Back 23

it is the second smaller division of the brain. It is located below

Front 24

Cerebellum

Back 24

it is responsible for the body balance, posture, and the coordination of movement

Front 25

Brain Stem

Back 25

The brain stem is located behind the cerebellum. It is a stalk like structure that connects the cerebrum with the spinal cord.

Front 26

Medulla Oblongata

Back 26

Is the bottom part of the brain stem. It serves as the site of connection between the brain and spinal cord. Just above the medulla is the Pons. Above the pons lies the midbrain. The pons connects the two hemispheres of the cerebellum.

Front 27

Thalamus

Back 27

it relays impulses from one part of the brain to another.

Front 28

Hypothalamus

Back 28

it regulates internal conditions of the body such as temperature, hunger, pain and pressure.

Front 29

Spinal Cord

Back 29

is one of the primary portions of the central nervous system. It allows signals to be sent from the brain to the arts of the body, it also receives messages from the parts of the body to the brain.

Front 30

Spinal Cord

Back 30

The brain and the spinal float in a fluid called cerebrospinal fluid.
