The Human Nervous System
The two main divisions of the human nervous system
What are the central nervous system (CNS) and peripheral nervous system (PNS)?
This structure links the brain with the rest of the body
What is the spinal cord?
This lobe is responsible for decision making, planning, and voluntary movement
What is the frontal lobe?
This area of the brain controls speech production
What is Broca's area?
This neurotransmitter is involved in muscle movement and memory
What is acetylcholine?
The CNS is made up of these two structures
What are the brain and spinal cord?
The spinal cord's main function is to do this
What is transmit information between the brain and body?
This lobe processes visual information
What is the occipital lobe?
This area of the brain is responsible for understanding language
What is Wernicke's area?
This neurotransmitter is involved in muscle movement and memory
What is acetylcholine?
The PNS consists of these two subdivisions
What are the somatic and autonomic nervous systems?
The spinal reflex allows this kind of response
What is a quick, automatic response without brain involvement?
This lobe processes touch, temperature, and pain
What is the parietal lobe?
This region connects Broca's and Wernicke's areas
What is Geschwind's territory?
This neurotransmitter is primarily excitatory
What is glutamate (Glu)?
This part of the nervous system controls voluntary movement of skeletal muscles
What is the somatic nervous system?
The pathway involved in a spinal reflex includes these three types of neurons
What are sensory, interneuron, and motor neurons?
This lobe is involved in hearing and memory
What is the temporal lobe?
Voluntary movement begins in this brain area
What is the primary motor cortex?
Low levels of this neurotransmitter are linked to depression
What is serotonin?
This part of the nervous system controls automatic body functions like heart rate and digestion
What is the autonomic nervous system?
An example of a spinal reflex
What is pulling your hand away from a hot surface?
Damage to the occipital lobe would most likely affect this sense
What is vision?
Coordination and balance are managed by this structure
What is the cerebellum?
Blocking acetylcholine at the neuromuscular junction can result in this effect
What is paralysis?
eg. Botox - a toxin stopping muscle activation
