Functions of the Nervous System |
1. Sensory 2. Integration 3. Motor Output |
|
|
Carry information in the Nervous System |
Nerve Cells (Neurons) |
|
|
Three Main Parts of a Neuron |
1. Dendrite 2. Soma (cell body) 3. Axon
|
|
|
Impulse Travels |
Dendrite-> Soma (cell body)->Axon |
|
|
Three Kinds of Neurons and Functions |
1.Sensory- Senses 2. Motor- Muscles & Movements 3. Inter Neurons- THinking & Memory Functions |
|
|
Impulses Traveled Between Neurons |
Dendrites->cell body->axon->Syn->Dendrites |
|
|
Two Divisions of the Nervous System |
1.Central- Brain and spinal 2. Peripheral- motor and Sensory |
|
|
Spinal Cord |
Bundle of sensory neurons and motor neurons |
|
|
How many Neurons in the brain |
100 Billion |
|
|
3 Main parts of the brain |
Cerebrum- Thinking, Reasoning, memory 2. cerebellum- Balance and movement 3. Brain stem- controls organs and involuntary movements |
|
|
Functions of the peripheral nervous system. Pairs? |
Connects all organs and muscles to the central nervous system. 43 pairs of neurons Bundled |
|
|
Somatic |
Voluntary |
|
|
Autonomic |
Involuntary |
|
|
Reflex |
Responsible to a stimulus that occurs without the brains involvement |
|
|
Reflex Travels |
Centry-motor-brain after the message is received. |
|
|
Spinal Cord injuries |
Cannot repair itself, when it is cut or damaged. it damages all the muscles and sensory neurons in that region |
|
|
Frontal Temporal lobe Parietal Lobe Ocipitial lobe |
|
|
Frontal |
Carries out higher mental process such as thinking, decision making, and planning
|
|
|
parietal |
Sensory information that has to do with taste, temp. and touh |
|
|
Temporal |
Auditory information from the ears |
|
|
occipital |
Visual information from the eyes |

|
|
Cerebrum |
largest part that controls thought and action
|
|
|
Cerebullum |
At the bottom and is used for balance and posture, motor learning |
|
|
Medulla |
Hind brain and is responsible for autonomic functions |
|
|
Brain Stem |
Spinal cord and respiration heart rate and digestion |
|
|
Hypothalamus |
Nervous and endocrine above the brain stem |
|
|
Pituitary gland |
below the brain pea sized and produces hormones and endocrine system |
|
|
Thalamus |
center of the brain and relay motor sensory |
|
|
Midbrain |
Auditory and visual |
|
|
Corpus Callosum |
Center and communication |
|
|
pons |
Bridge above Medulla and Nervous system |
|

Largest portion thought and function |
|
|
neuron |
|
|
gyrus sulcus and fussure |
