Anatomy of a Cell
The name of the cell in the nervous system that is responsible for carrying information through the nervous system.
What is a neuron?
The two systems that control homeostasis in the body.
What are the nervous system and endocrine system?
The organ in the body responsible for controlling most of the functions of the body.
The number of pairs of nerves of the peripheral nervous system.
The system responsible for hormone release and regulation.
What is the endocrine system?
The branched portion of a neuron that picks up information.
What is a dendrite?
The three components of the overall nervous system.
What are the brain, spinal cord, and nerves?
The thick column of nervous tissue linking the brain to most of the nerves in the body.
What is the spinal cord?
The number of pairs of nerves that begin in the brain and extend out to parts of the head.
What is 12?
The organ responsible for producing and releasing chemicals via ducts or into the bloodstream.
What are glands?
The part of the neuron that receives information from the dendrite and sends it away from the cell.
What is the axon?
The part of the nervous system that includes the brain and spinal cord and controls most of the functions of the body and mind.
What is the Central Nervous System?
The three main parts of the brain.
What are the cerebrum, the cerebellum, and the medula?
The part of the PNS responsible for voluntary action.
What is the somatic nervous system?
The gland deep in the brain responsible for sending out nerve and chemical signals to control sleep, hunger, and other basic functions.
The three types of neurons.
What are the sensory, interneuron, and motor neurons?
The part of the nervous system that contains a network of nerves and branches out through the body.
What is the peripheral nervous system?
The part of the brain responsible for involuntary actions.
What is the medulla?
The part of the PNS responsible for involuntary actions.
What is the autonomic system?
The gland responsible for receiving signals from the hypothalamus and releasing hormones to signal other glands.
The junction where one neuron can transfer an impulse from one neuron to another.
What is the junction?
The neuron type responsible for carrying messages from one neuron to another.
What is the interneuron?
The part of the brain responsible for motion, balance, and learning new things.
What is the cerebellum?
The automatic response that occurs without conscious control to a stimulus event.
What is a reflex?
The phenomenon when a hormone reaches a certain level in the blood and the endocrine system produces a signal to stop the release of the hormone.
What is negative feedback?
