a specialized cell transmitting nerve impulses
Chemicals that transmit information from one neuron to another
chemical messengers that travel in the bloodstream to other tissues and organs
The endocrine system's most influential gland. Under the influence of the hypothalamus it regulates growth and controls other endocrine glands.
Both an endocrine and exocrine gland. Produces digestive enzymes & secretes insulin and glucagon into the bloodstream to help regulate blood glucose levels.
A protein hormone synthesized in the pancreas that regulates blood sugar levels by facilitating the uptake of glucose into tissues
A protein hormone synthesized in the pancreas that regulates blood sugar levels by facilitating the release of glucose from tissues
An extensively branched glucose storage polysaccharide found in the liver and muscle of animals; the animal equivalent of starch.
the form of sugar that circulates in the blood and provides the major source of energy for body tissues.
Branchlike parts of a neuron that are specialized to receive information.
A threadlike extension of a neuron that carries nerve impulses away from the cell body.
covers the axon of some neurons and helps speed neural impulses
the process by which a certain function is regulated by the amount of the substance it produces
secrete chemical substances into ducts that lead either to other organs or out of the body

the male sex hormone that signals certain physical changes at puberty and controls the maturation of sperm
neurons that carry incoming information from the sensory receptors to the brain and spinal cord
neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs
neurons that carry outgoing information from the brain and spinal cord to the muscles and glands
A large structure of the hindbrain that controls fine motor skills.
Area of the brain responsible for all voluntary activities of the body
an extension of the spinal cord into the skull that coordinates heart rate, circulation, and respiration
protein that detects a signal molecule and performs an action in response
the message carried by a neuron
