Electrical Activity
Term
Autonomic Nervous System is divided into two systems:
Definition
Sympathertic and Parasymthetic
Term
How many chromosomes do we have?
Definition
46 chromosomes, 23 pairs
Term
How do we learn about the brain?

Images of the brain by computers, people with head injuries, effects of electrical stimulation of the brain.
Term
A useful study for showing that influence of heredity and environment examines what kind of participants?
Definition
Twins that have been raised apart.
Term
Outer layer of the brain:
Definition
Cerebral Cortex
Term
Creating language has its origin where in the brain?

Definition
Producing and understanding speech.
Term
Are people right-brained or left-brained?
Definition
Both hemispheres work together; both involved in logical, creativity, and intuition.
Term
Label main structures of a neuron.
Definition
Term
Neuron: Axon
Definition
Transfers electrical ipulse signals from the cell body to the synapse.
Term
Neuron: Dendrites
Definition
Receive electrical impulses from neighboring neurons.
Term
Neuron: Myelin Sheaths
Definition
Cover the axon and work like insulation to help keep electrical signals inside the cell, which allows them to move quickly.
Term
Neuron: Nucleus
Definition
Contains the cell's DNA
Term
Vocab - Neuron
Definition
a nerve cell; the basic building block of the nervous system
Term
Vocab - Dendrite
Definition
the branch-like extensions of a neuron that receive impulses and conduct them toward the cell body
Term
Vocab - Axon
Definition
a long tube-like structure attached to a neuron that transmits impulses away from the neuron cell body
Term
Vocab - Somatic Nervous System
Definition
the division of the peripheral nervous system that connect the central nervous system with sensory receptors, muscles, and the skin
Term
Vocab - Autonomic Nervous System
Definition
the subdivision of the peripheral nervous system that regulates body functions, such as respiration and digestion
Term
Vocab - Medulla
Definition
The lowest section of the brainstem (at the top of the spinal cord); it controls automatic functions including heartbeat, breathing, etc.
Term
Vocab - Cerebellum
Definition
The part of the brain below the back of the cerebrum. It regulates balance, posture, voluntary movement, and muscle coordination.
Term
Vocab - Thalamus
Definition
the structure of the brain that relays messages from sense organs to the cerebral cortex
Term
Vocab - Cerebrum
Definition
the large mass of the forebrain, consisting of two hemispheres
Term
Vocab - Endocrine System
Definition
Term
Vocab - Association Area
Definition
Term
Vocab - Hormone
Definition
Term
Frontal Lobe of the Cerebrum
Definition
The top, front regions of each of the cerebral hemispheres. They are used for reasoning, emotions, judgement, and voluntary movement.
Term
Occipital Lobe of the Cerebrum
Definition
The region at the back of each cerebral hemisphere that contains the centers of vision and reading ability (located at the back of the head)
Term
Parietal Lobe of the Cerebrum
Definition
The middle lobe of each cerebral hemisphere between the frontal and occipital lobes; it contains important sensory centers (located at the upper rear of the head).
Term
Temporal Lobe of the Cerebrum
Definition
The region at the lower side of each cerebral hemisphere; contains centers of hearing and memory (located at the sides of the head).
Term
Spinal Cord
Definition
A thick bundle of nerve fibers that runs from the base of the brain to the hip area, runnin through the spine.
Term
Pituitary Gland
Definition
A gland attached to the base of the brain (located between the Pons and the Corpus Callosum) that secretes hormones.
Term
Pons
Definition
The part of the brainstem that joins the hemispheres of the cerebellum and connects the cerebrum with the cerebellum. It is located above the Medulla Oblongata.
Term
Corpus Callosum
Definition
A large bundle of nerve fibers that connect the left and right cerebral hemisphere. In the lateral section, it looks a bit like a "C" on its side.
