The Systems
The system of nerves which carries information from the body’s receptors to the CNS.
What is the Sensory Nervous System?
These are composed of a cell body, dendrites, and axons.
What are Neurons?
This stuff in the brain is composed mostly of the axons of the neurons in the Grey Matter.
What is White Matter?
These are sensitive to salty, bitter, sweet, sour, and unami
What are Taste Buds?
The left hemisphere of the brain controls _______________________.
What is the right side of the body?
The system of nerves which carries instructions from the CNS to the body’s smooth muscles, cardiac muscles and glands
What is the Autonomic Nervous System?
These carry signals toward the cell body of a neuron.
What are Dendrites?
This part of the brain controls the movement of voluntary muscles
What is the Cerebellum?
This converts the back and forth motion of the ear ossicles into electrical signals that the brain interprets as sound.
What is the Cochlea?
The part of the Autonomic Nervous System activated by threatening stressors to speed up the heart rate and raise the blood pressure.
What is the Sympathetic Division?
The system of nerves which carries instructions from the CNS to the skeletal muscles.
What is the Motor Nervous System?
A gap between the axon of a neuron and the receiving cell.
What is a Synapse?
This part of the brain controls most of the high-level thinking skills such as reasoning
What is the Cerebrum?
This changes the shape of the lens in the eye to adjust focus
What is the Ciliary Muscle?
The right hemisphere of the brain controls _______________________.
What is the left side of the body?
The Autonomic, Sensory, and Motor Nervous System are all part of the _______________.
What is the Peripheral Nervous System?
These support the neuron by performing various tasks so that the neurons can do their job.
What are Neuroglia?
This stuff in the brain is composed mostly of neuron cell bodies
What is Grey Matter?
The sense that is everywhere on your body.
What is the sense of touch?
The part of the Autonomic Nervous System that activates the relaxation response to slow the heart rate and lower the blood pressure.
What is the Parasympathetic Division?
The brain and spinal cord are part of the _____________________________.
What is the Central Nervous System?
These carry signals away from a neuron’s cell body
What are Axons?
This part of the brain allows the different hemispheres of the brain to communicate
What is the Corpus Callosum?
When we "smell" something, our olfactory sensory cells are detecting _____________?
What are particles? (Tiny airborne chemical particles)
Chemicals which travel across a synapse, transmitting a signal from the end of one axon to a receiving neuron.
What is a Neurotransmitter?
