1. Myocardium: specialized muscle, unique ability to contract on its own. w/out stimulation by nerves
2. The heart has four chambers, what are they?: 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.
3. Right Ventricle of the heart: Sends deoxygenated blood to the lungs.
4. Left Ventriclue of the heart: Sends oxygenated blood into the body or peripheral curculation (THE
BODY)
5. Vessels and Valves: 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.
6. Neurons: cells of the nervous system responsible for conducting nerve impulses within the brain as well as from
one part of the body to another.
7. Action potential: The nerves threshold of stimulus
8. Synapse: A junction between two neurons or to another structure such as a muscle.
9. Terminal Button: the bulge at the end of the nerve touches the next nerve in the nerve pathway.
10. Gap between two nerves: synaptic cleft
11. Central Nervous System: overall control center of the body and consists of the brain and spinal cord.
12. Cerebral Cortex: 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.
13. The Core of the Brain: 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.
14. Cerebellum: Coordinating center for both sensory receptors, such as those for vision and hearing as well as
coordination of movement.
15. Brainstem consists of what?: Midbrain, pons, and medulla oblongata
16. Cranial nerves: peripheral nerves that have their origin at the base of the brain.
17. Optic Nerve: 2nd cranial nerve, allows us to see
18. Olfactory Nerve: 1st cranial nerve and allows us to smell
19. Auditory Nerve: 8th cranial nerve, allows us to hear
20. Trigeminal Nerve: 5th cranial nerve, supplies sensation to the teeth and jaws, also has motor brances that
supply the muscle of mastication.
21. Facial Nerve: 7th cranial nerve, supplies motor fibers to the muscles of facial expression and allows us to
smiles, frown, wrinkle our brow.

22. What trigeminal nerves "three paired" division consist of?: Opthalmic, Maxillary and
Mandibular
23. Autonomic Nervous System regulates what?: Internal Organs, keeping the bodys internal
environment in a relatively constant state (homeostasis)
24. Sympathetic System: More dynamic and tends to speed up processes in their effects on the various
organs (Physical activity in response to stress) "Fight or Flight" summarizes the various actions of this system.
25. Parasympathetic System: Maintains the resting or vegetative state and tends to slow processes on
various organs. "Couch potato states"
26. What drugs depress the vital centers, resulting in hypotension and respira-
tory depression?: Barbiturates and propofol
27. What drugs stimulates the vital centers and causes inscrease in blood pres-
sure and pulse?: Ketamine
28. Superior vena cava: Above the heart the blood is returned
29. Inferior vena cava: Below the heart the blood is returned
30. Coronary Sinus: a wide venous channel about 2.25 centimeters in length that receives blood from the
coronary veins and empties into the RIGHT atrium
31. Arteries: All vessels leading away from the heart
32. Veins: All lead to the heart
33. Pulmonary Artery: carrys blood from the right ventricle of the heart to the lungs for oxygenation
34. Hemoglobin: Red protein tranports oxygen in the blood of vertebrates
35. Angina Pectoris: "Chest Pain"
36. Myocardial Infraction: Heart attack or coronary
37. Arterioles: "smaller arteries"
38. Capillaries: "Microscopic arteries"
39. Venules: the smallest veins
40. Lumen: arterys hollow core
41. stroke volume: usually 60ml of blood and is the amount of blood pumped by the left ventricle in each beat
42. Cardiac Cycle: One contraction and relaxation of the atria and ventricles follow by a short pause.
43. Bradycardia: any rate below 60 beats per min
44. Tachycardia: any rate greater than 100 beats per min
45. Automacity: unique property of myocardial cells to generate a discharge and contract their own with out
stimulation by nerves
