Psychology

Nervous system

Central Nervous System (CNS) (Brain, spinal cord)

Peripheral Nervous System (Neurons)

Autonomic Nervous System

Neurons

Sensory Neurons (Afferent) (receives sensory information from sense organs, e.g. skin)

Motor Neurons (Efferent) (sends movements to the muscles to to)

Physical Structure

Spinal Cord

Brain

Neurons

Inter neurons (transmitters)

Neural Structure

Brain

Axon

Dendrites

Mylen Sheath (insulating layer and allows impulses to transmit quickly)

Axon Terminals

Terminal Buttons

Receptor Sites

Forebrain (Front of brain, in charge of high order thinking)

Midbrain

Hindbrain (Unconscious and fundamental to survival)

Somatic Nervous System

Sympathetic NS (Flight, fight, freeze)

Parasympathetic NS (Calming down from (FFF))

Spinal reflex (reflex arc, where the neural impulse goes to the spine and back rather than to the brain)

Neural impulse

Synapse

Synaptic Gap

Pre-synaptic neuron

Post-Synaptic neuron

Neurotransmitters

Hypothalamus (regulates appetite thirst, sex drive, sleep-wake cycle)

Thalamus (redirects all sensory information (except smell))

Cerebrum (two largest hemispheres that move information around the brain)

Reticular information (filters information and activates alertness)

Cerebellum (helps co-ordinate voluntary movements and balance)

Medulla (regulates internal bodily systems, heart rate, breathing)

Pons (sleep-wake cycle, arousal, alertness, breathing, some muscle movements, relays information)

Right hemisphere (creative ability, visual awareness, body language, recognition)

Left hemisphere (reading, writing, speaking, patterns, logical reasoning)
