Nervous System Part 2

Front 1

Brainstem

Back 1

Consists: Medulla Oblongata, Pons, and Midbrain.

Function: Alertness, Arousal, Breathing, Blood Pressure, Contains Most of the Crainal Nerves, Digestion, Heart Rate, Relays Information Between the Peripheral Nerves and Spinal Cord to the Upper Parts of the Brain.

Front 2

Diencephalon

Back 2

Contains the Hypothalamus, and the Thalamus.

Front 3

Hypothalamus

Back 3

Consists mainly of the posterior pituitary gland, pituitary stalk and gray matter. Major center for controlling the ANS, therefore controls most of the functions of internal organs. Controls hormome secretion from the posterior & anterior pituitary glands. Contains centers for controlling appetite, wakefulness pleasure...

Front 4

Thalamus

Back 4

Dumbellshaped mass of gray matter in each cerebral hemisphere. Relays sensory impulses to cerebral cortex sensory areas. In some way produces the emotions of pleasantness and unpleasantness associated with sensations.

Front 5

Cerebellum

Back 5

Second Largest part of human brain. Balance, Attention Span, Posture, smooth movements... (Sarah Bellum the Southern Belle)

Front 6

Cerebrum

Back 6

Largest part of human brain. Outer layer of gray matter is cerebral cortex. Interior consists of white matter. Functions: Mental processes of all kinds, sensations, conciousness, memory and voluntary control of movements.

Front 7

Cerebrovascular Accident (CVA)

Back 7

A Hemmorage due to the stopping of blood flow through the cerebral blood vessels, A.K.A: A Stroke.

Front 8

Cerebral Palsy

Back 8

Condition in which damage to motor control areas of the brain before, during or shortly after birth causes paralysis of one or more limbs.

Front 9

Dementia

Back 9

Syndrome that includes progressive loss of memory, shortened attention span, personality changes, reduced intellectual capacity and motor control deficit.

Front 10

Alzheimers Disease (AD)

Back 10

Brain Disorder of the middle and late adult years characterized by dementia.

Front 11

Huntington Disease

Back 11

A Inherited Disorder characterized by chorea (purposeless movement) progressing to severe dementia.

Front 12

HIV Vuris

Back 12

Also causes AIDs, and can affect neurons, thus leading to dementia.

Front 13

Preganglionic Autonomic Neurons

Back 13

Conduct from Spinal cord or Brain Stem to an automatic ganglion.

Front 14

Postganglionic Neurons

Back 14

Conduct from autonomic ganglia to cardiac muscle, smooth muscle, and glandular epithelial tissue.

Front 15

Autonomic or Visceral Effectors

Back 15

Tissue to which autonomic neurons conduct impulses (cardiac, smooth muscle, glandular epithelial tissue)

Front 16

Seizure

Back 16

Sudden burst of abnormal neuron activity, that results in temporary changes in brain function.

Front 17

Epilepsy

Back 17

Many forms, all characterized by recurring seizures.

Front 18

Bells Palsy

Back 18

Paralysis of facial features due to damage of the facial nerve (Nerve VII)

Front 19

Spinal Nerves

Back 19

Structure: Contains dendrites of sensory neurons and axons of motor neurons.
Function: Conducts impulses necessary for sensation and voluntary movements.
