Nerve cell; specialized for carrying messages throughout the nervous system
Place where one bone attaches to another bone
Chemical used by a neuron to transmit an impulse across a synapse to another cell
Tough connective tissue that holds bones together in a joint
Includes the brain and spinal cord; processes information and creates a response that is delivered to the body
Extension of the cell body of a neuron that carries impulses from the environment or from other neurons toward the cell body
Think middle muscles layer of the heart
Down
Reversal of charges across the cell membrane of a neuron; also called a nerve impulse
Upper chamber of the heart that receives blood from the rest of the body
Long fiber carries impulses away from the cell body of a neuron
Point at which a neuron can transfer an impulse to another cell
The bones of the arms and legs along with the bones of the pelvis and shoulder area
Type of connective tissue that supports the body and is softer and more flexible than bone
Soft tissue found in bone cavities
Minimum level of a stimulus that is required to cause an impulse
Largest part of a typical neuron, contains the nucleus and much of the cytoplasm
