Basic units of the nervous system
Transmit information from the sensory cells called receptors to the brain.
Nerve cells that connect other neurons with one another.
Transmit commands from interneurons to the glands and muscles of the body.
Anatomy of a neuron
Neurotransmitter that can excite nearly every neuron in the nervous system
Neurotransmitter that play an inhibitory role.
Neurotransmitter involved in thought, feeling, motivation, and behaviour
Neurotransmitter involved in regulation of mood, sleep, eating, arousal and pain.
Neurotransmitter involved in learning and memory.
Neurotransmitter that elevates mood and reduces pain.
A collection of glands that secrete chemicals, called hormones, directly into the bloodstream.
An oval structure in the brain often called the master gland because it stimulates and regulates other glands
Located in the neck, releases hormones that control growth and metabolism
Located in the kidneys. Secretes adrenaline and other hormones during emergencies.
Located near the stomach, produces hormones that control blood-sugar levels
Glands that influence sexual development and behaviour.

Central nervous system
Consists of brain and spinal cord
Peripheral nervous system
Consists of neurons that convey messages to and from the CNS.
Somatic nervous system & Autonomic nervous system
Somatic nervous system
Transmits sensory information to the central nervous system and carries out its commands
Autonomic nervous system
Conveys information to and from internal bodily structures that carry out basic life support such as digestion and respiration.
Includes Sympathetic nervous system & Parasympathetic nervous system.
Sympathetic nervous system
Activated in response to threats.
Parasympathetic nervous system
Supports the more mundane activities such as regulating blood-sugar, saliva, and eliminating wastes.
Three parts of the Brain
Medulla oblongata (medulla)
Parts of reticular formation
The extension of the spinal cord to the brain. Essential to life, controlling vital functions such as heartbeat, circulation and respiration
Large structure at back of brain involved in movement as well as other functions.
