Test 2 Biological Foundations

Front 1

Homeostasis

Back 1

The Tendency of systems to Maintain a steady internally balanced state

Front 2

Hormones

Back 2

Secretions from endocrine glands that help regulate bodily processes

Front 3

Cerebellum

Back 3

A structure in the hindbrain unvolved in controlling cordination and balance

Front 4

Action Potential

Back 4

Abrupt change from a negative to a possitive charge of a nerve cell also called a neural impulse

Front 5

Sympathetic Nervous system

Back 5

Branch of the autonomic nervous stsem that accelerated bodily processes and releases the stores of energy nedded to meet increased physical demands

Front 6

Neurotransmitters

Back 6

Chemical Messengers that transport nerve impulses from one nerve cell to another

Front 7

Neurons

Back 7

Basic building blocks of the nervous system-the body's wiring through wich messages are transmitted within the nervous system (Nerve Cells)

Front 8

Hypothalamus

Back 8

small pea-sized structure in the forebrain that helps regulate many vital bodily functions including body temp and reproduction as well as emotional states agression and response to stress

Front 9

Genes

Back 9

Basic units of heredity that contain the individuals genetic code

Front 10

Dendrites

Back 10

Tree like structures projecting from the soma that RECEIVE neural MESSAGES from neighboring neurons

Front 11

Cerebral Cortex

Back 11

The wrinkled outer layer of gray matter that covers the cerebral hemispheres: controls higher mental functions such as thought and launguage

Front 12

Central Nervous System

Back 12

The part of the nervous system that consists of the brain and spinal cord

Front 13

Axon

Back 13

Tubelike part of a neuron that carries messages away from the cell body toward other neurons

Front 14

Thalamus

Back 14

A structure in the forebrain that serves as a relay station for sensory info and that playsa key role in regulating state of wakefulness and sleep

Front 15

Synapse

Back 15

The small fluid-filled gap between neurons through wich neurotransmitters carry neural impulses

Front 16

Schizophrenia

Back 16

Severe chronic psychological disorder, characterized by DISTURBANCES in THINKING PERCEPTION EMOTIONS and BEHAVIOR

Front 17

Peripheral Nervous System

Back 17

the part of the nervous system that connects the spinal cord and brain with the sensory organs muscles and glands (bodys link to outside world)

Front 18

Autonomic Nervous System

Back 18

the part of the peripheral nervous system that automatically regulates involuntary bodily processes such as breathing, heart rate and digestion

Front 19

Limbic System

Back 19

Formation of structures in the forebrain that includes the hippoicampus andygdala and parts of the thalamus and hypothalamus; is involved in memory and emotional processing

Front 20

Parasympathetic Nervous System

Back 20

Branch of the autonomic nervous system that regulates bodily processes, such as digestion that replenish stores of energy
