| Function | Part |
|---|
| Bushy, branching extensions of a neuron | |
| Lies above ears; includes auditory areas, each side receives information from opposite ear | |
| Lies at top of head and toward rear; receives sensory information (touch and body position) | |
| Neurons that carry outgoing information from the brain and spinal cord to muscles and glands | |
| Layer of fatty tissue encasing fibers of neurons; enables greater transmission speed of neural impulses | |
| Neurons that carry incoming information from sensory receptors to brain and spinal cord | |
| Chemical messengers that cross synaptic gaps between neurons; bind to receptor sites on receiving neuron | |
| 'Little brain'; habitual muscle movements, basic biological functions | |
| Covers hemispheres, ultimate control and information-processing center | |
| Lies behind forehead; speaking, muscle movements, making plans, judgment | |
| Controls blood pressure, heart rate, breathing | |
| Part of limbic system, controls body temperature, libido, hunger, thirst, endocrine system, biological rhythms; pleasure center, reward center | |
| Connects brain's hemispheres; removal can stop seizures | |
| Part of limbic system, fear and aggression | |
| Lies at back of head; receives information from visual fields | |
| | Function | Part |
|---|
| Oldest part and central core of brain, responsible for automatic survival functions | |
| Part of limbic system, receives sensory signals from spinal cord and sends them to other areas of the brain | |
| Pathway of neural fibers to and from brain, controls reflexes | |
| Neurons within the brain and spinal cord | |
| Bundled axons that form neural 'cables' | |
| A nerve cell | |
| Helps control arousal, filters stimuli going to thalamus and relays information to other areas | |
| Connects hindbrain with midbrain and forebrain; control of facial expressions | |
| Neural system associated with emotions and drives | |
| Lies at rear of frontal lobe; controls voluntary movements | |
| Extension of a neuron, ending in branching fibers | |
| Master endocrine gland | |
| Part of limbic system, new memories, before storage | |
| Junction between axon tip of one neuron and dendrite of another; small gap | |
| Area at front of parietal lobe; registers and processes body touch and movement sensations | |
