Daance Module 1, Questions with Correct Answers (Grade A+)
Question 1: Myocardium
Answer: specialized muscle, unique ability to contract on its own. w/out stimulation by nerves
Question 2: The heart has four chambers, what are they?
Answer: Two upper chambers receive blood are called Atria. The left atrium receives blood from the lungs
via the pulmonary vein and is oxygen-rich; the right atrium receives blood from the peripheral curculation
(THE BODY) and is oxygen-poor.
Question 3: Right Ventricle of the heart
Answer: Sends deoxygenated blood to the lungs.
Question 4: Left Ventriclue of the heart
Answer: Sends oxygenated blood into the body or peripheral curculation (THE BODY)
Question 5: Vessels and Valves
Answer: blood flows through the body in only one direction. The right side of the heart is filled with
deoxygenated blood while the left side is filled with oxygenated blood.
Question 6: Neurons
Answer: cells of the nervous system responsible for conducting nerve impulses within the brain as well as
from one part of the body to another.
Question 7: Action potential
Answer: The nerves threshold of stimulus
Question 8: Synapse
Answer: A junction between two neurons or to another structure such as a muscle.
Question 9: Terminal Button
Answer: the bulge at the end of the nerve touches the next nerve in the nerve pathway.
Question 10: Gap between two nerves
Answer: synaptic cleft

, Question 11: Central Nervous System
Answer: overall control center of the body and consists of the brain and spinal cord.
Question 12: Cerebral Cortex
Answer: Responsible for such essential functions as thought, learning, memory, consciousness, the feeling
of sensations such as pain or heat and the initiation of muscle movement.
Question 13: The Core of the Brain
Answer: Impulses pass through on their way to or from the cerebral cortex. Relay station between sensory
inputs from the periphery of the body to the cerebral cortex.
Question 14: Cerebellum
Answer: Coordinating center for both sensory receptors, such as those for vision and hearing as well as
coordination of movement.
Question 15: Brainstem consists of what?
Answer: Midbrain, pons, and medulla oblongata
Question 16: Cranial nerves
Answer: peripheral nerves that have their origin at the base of the brain.
Question 17: Optic Nerve
Answer: 2nd cranial nerve, allows us to see
Question 18: Olfactory Nerve
Answer: 1st cranial nerve and allows us to smell
Question 19: Auditory Nerve
Answer: 8th cranial nerve, allows us to hear
Question 20: Trigeminal Nerve
Answer: 5th cranial nerve, supplies sensation to the teeth and jaws, also has motor brances that supply the
muscle of mastication.
