Structure I
This part of the brain provides hearing, smell and memory
What is the temporal lobe?
This part of the brain controls conscious activity
What is the cerebrum?
This axonal protective coating forms the white matter
What is a myelin sheath?
When the cell membrane has a net positive chare on the outside and a net negative charge on the inside
What is resting potential?
The somatic nervous system and the automatic nervous system are both parts of this nervous system
What is the peripheral nervous system?
Sensory neurons are part of the ________ nervous system
What is the peripheral nervous system (PNS)?
This part of the brain controls body coordination
What is the cerebellum?
The hypothalamus is part of the ___________ nervous system
What is the central nervous system (CNS)?
This is the gap between the axon terminal of one neuron and the dendrite of the next neuron
What is the synaptic cleft?
Sympathetic and parasympathetic are both parts of this nervous system
What is the autonomic nervous system?
This part of the brain links the nervous and endocrine systems
What is the hypothalamus?
Motor neurons are part of the ___________ nervous system
What is peripheral?
This part of the brain keeps a person awake and alert
What is the thalamus?
The synaptic cleft is bridged by ______________
What are neurotransmitters?
This is when the nerve impulse from the sensory receptor travels up the sensory neuron to the interneuron. Instead of sending the impulse on to the brain like a normal neural impulse, the interneuron sends an impulse down a motor neuron to the effector.
What is a reflex arc?
An injury to this part of the brain is likely to affect heart rate, blood pressure, and respiration
What is the brain stem?
This part of the brain is used for reasoning, planning, and verbal communication
What is the frontal lobe?
This part of the brain processes visual stimuli
What is the occipital lobe?
An example of this concept is when dust particles collide with your skin every second, but you don't notice them
What is a threshold?
These ions are responsible for the charge on the side of the cellular membrane of a neuron at resting potential
What are a sodium cations?
This part of the brain provides environmental awareness
What is the parietal lobe?
These meninges would be penetrated during a spinal tap (a procedure using a needle to remove some CSF)
What are the arachnoid mater and dura mater?
This part of the brain controls most basic homeostatic processes
What is the brain stem?
When the protein channels in a neuron's cell membrane open in response to a stimulus
What is an action potential?
This structure is likely injured when a patient comes into the hospital with a lack of feeling in one leg though he can still move it
What is a sensory neuron (or the axon of a sensory neuron)?
