Front 1

Subdivision and functions of nervous system

Back 1

Central Nervous System (CNS)- Brain and Spinal Cord. Perephrial Nervous System cranial and spinal nerves (PNS) PNS then branches off into Motor (efferent) and Sensory (afferent). Motor braches into Automic nervous system (ANS) and Somatic nervous system. ANS then branches into Para and Sympathetic.

Front 2

Compare similarites and differences between nervous and endocrine system

Back 2

Similarities- Both maintain homeostasis. Both secrete chemicals n-neurotransmitters and e- hormones.
Differences- E- system response takes longer N- system response faster. N wires (neurons) e-wireless (hormones).

Insulation/fat PNS

Satellite Cell

Back 4

Insulation/Fat PNS

Front 5

Oligodendrocytes

Back 5

Wrap neurons in insulation CNS

Front 6

astrocytes

Back 6

cling to neurons and their synaptic endings and cover capilaries and vessles. Social workers (they support) CNS

Front 7

ependymal

Back 7

Line ventricles of brain. Help move/fan cerebral spinal fluid (CSF) CNS

Front 8

Microglial

Back 8

Phagotize (cleanup) dead nervous tissue microorganisms, and other foreign matters. Fight and clean. CNS

Front 9

Describe structure and function of neuron

Back 9

excitable cells that transmit electrical signals. Together with neuroglial cells they comprise nervous tissue making up nervous system.

Front 10

Mylenation of CNS

Back 10

oligodendrocytes make the myelin, they cooperate in the formation of a myelin sheath along the axon, this is the process of myelination. Each oligodendrocyte produces segments of several axons

Front 11

Mylination of PNS

Back 11

schwann cells make the myelin, each schwann cell can myelinate one segment of a single axon and they work together ot form the myelin sheath

Front 12

Polarization of a neuron

Back 12

a neuron at rest is considered polarized due to its non zero potential.

Front 13

hyperpolarization of a neuron

Back 13

makes cell more polarized and unable to fire. Can't repolarize.

Front 14

repolarization of a neuron

Back 14

Repolarization –a change that brings the cell back to (or closer to) resting potential, regardless of direction. Karen in Nancy out.

Front 15

Depolarization of a neuron

Back 15

Potential closer to zero. less polarized. More likely to fire.

Front 16

Function/location of precentral lobe

Back 16

Motor- Frontal Lobe- the primary motor area of the cerebral cortex

Front 17

Function/location of post central lobe

Back 17

primary sensory area of the cerebral cortex. frontal lobe

Front 24

function of Thalamus

Back 24

Gateway of cerebral cortex. All sensory that goes to the brain goes passes through here.

Front 25

Funtion of hypothalamus

Back 25

Hormone secretion. Autonomic effects, thermoregulation, food and water intake, sleep, memory, emotional behavior.

Front 26

Pituitary Gland

Back 26

Master Gland tells other glands to release hormones

Front 27

Corpa quadrigemma

Back 27

4 nuclei. Visual reflex- Superior caliculus Hearing reflex Inferior caliculus

Front 28

Cerebellum

Back 28

Balance, complex motor activities.

Front 29

Medulla Oblongata

Back 29

Contains neural networks involved in a multitude of sensory and motor functions.
