Nervous System Anatomy

What does CNS and PNS stand for? Central nervous system and peripheral nervous system.
What are the parts of the CNS? Brain and spinal cord
Describe something that you do on a regular basis that your PNS controls. Feel/touch
What are the two divisions of the autonomic nervous system and what does each control? Sympathetic and parasympathetic. Sympathetic controls actions or movement and parasympathetic controls your emotions.
What are the three main types of neurons? What is the function of each? Sensory neuron – which control your sense of feeling(touch), motor neuron – controls your movement/actions, and inter neuron – sends messages to the CNS.
What is the function of the axon of a nerve cell? The dendrite? The axon conducts a nerve impulse away from a neuron cell body. The dendrite transmits impulses towards a neuron cell body.
What is a synapse? This is the junction between the axon of one neuron and dendrite or cell of another neuron.
Sketch a neuron and label the axon and the dendrite.
