Nervous system

Network of neurons in the body
CENTRAL NERVOUS System and PERIPHERAL NERVOUS SYSTEM

Central Nervous system

brain and spinal cord, "command central"

Peripheral Nervous System

connects CNS with rest of body through sensory and motor axons called nerves
"pick-up- and delivery"
1. somatic
2. Autonomic--> sympathetic (respond quick) + parasymapthetic

Endocrine System

Hormones, communication channel through bloodsteam (chemical postman)

Pituitary glad

growth;

master gland that regulates the endocrine glands.
Regulates many basic functions of the body
Controlled by the hypothalamus

Epinephrine

Fight or flight

Anterior pituitary

ovaries and testes

Thyroid

Metabolism

Adrenal glads

Fight or light

Pituitary glad

Oversees all endocrine responses

Electroencephalograph (EEG)

record brain waves, not precise

X-Ray soft issue 3-D

PET scanning

Brain activity

MRI

uses pulses of magnetic energy

What are the 3 layers of the brain

BRain stem, limbic system, cerebrum

Brain Stem

alertness level

Medulla

part of brain stem, breathing blood pressure and hear rate

Pons

Dreaming

Reticular Formation

alert and active brain

Thalamus

Direct incoming and outgoing sensory and motor traffic

Cerebellum

Coordination and balance

Limbic System

Emotion and memory (amygdala, hypothalamus)

Hippocampus

memory system 2 of em; longterm memory
Spatial memory

Amygdala

Fear and apprehension

Hypothalamus

Hunger and eating
blood analysis
LINK BETWEEn nervous system and endocrine system

The Cerebral Cortex

Thinking

The Cerebral Cortex

thinking Gray matter

Corpus Callosum

band of nerve cells connecting/ enabling communication between hemispheres

The Frontal Lobes

(prefrontal cortex) decision making, goal setting and follow though

Left Frontal Lobe

speech (broca's area)

Mirror Neuron

Fires response to observation of another person's actions

Left hemisphere

Analytic, sequential/ receives input from right visual field

Right hemisphere

Holistic, emotional, spatial/ receives input from

Cerebral Dominance

Tendency of each brain hemisphere to exert control over different functions
Language and Communication

DNA

made up of Genes

Nervous system & endocrine system

The body's two communication systems

Neuron

receive process and transmit information to other cells

Dendrite

Branched fiber that extends outward from the cell body and carries info into the neuron

Neurotransmitter

Chemical messenger that relays neural messages across the synapse. (hormones)

Plasticity

Nervous system's ability to adapt or change as the result of experience/ adapt to physical damage

Glial cell

Structural support, insulation covering (myelin sheath) of the axon for some neurons, facilitates the electrical impluse
