Myocardium - ANSWER: specialized muscle, unique ability to contract on its own.
w/out stimulation by nerves
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.
Right Ventricle of the heart - ANSWER: Sends deoxygenated blood to the lungs.
Left Ventriclue of the heart - ANSWER: Sends oxygenated blood into the body or
peripheral curculation (THE BODY)
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.
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.
Action potential - ANSWER: The nerves threshold of stimulus
Synapse - ANSWER: A junction between two neurons or to another structure such as
a muscle.
Terminal Button - ANSWER: the bulge at the end of the nerve touches the next nerve
in the nerve pathway.
Gap between two nerves - ANSWER: synaptic cleft
Central Nervous System - ANSWER: overall control center of the body and consists of
the brain and spinal cord.
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.
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.
, Cerebellum - ANSWER: Coordinating center for both sensory receptors, such as those
for vision and hearing as well as coordination of movement.
Brainstem consists of what? - ANSWER: Midbrain, pons, and medulla oblongata
Cranial nerves - ANSWER: peripheral nerves that have their origin at the base of the
brain.
Optic Nerve - ANSWER: 2nd cranial nerve, allows us to see
Olfactory Nerve - ANSWER: 1st cranial nerve and allows us to smell
Auditory Nerve - ANSWER: 8th cranial nerve, allows us to hear
Trigeminal Nerve - ANSWER: 5th cranial nerve, supplies sensation to the teeth and
jaws, also has motor brances that supply the muscle of mastication.
Facial Nerve - ANSWER: 7th cranial nerve, supplies motor fibers to the muscles of
facial expression and allows us to smiles, frown, wrinkle our brow.
What trigeminal nerves "three paired" division consist of? - ANSWER: Opthalmic,
Maxillary and Mandibular
Autonomic Nervous System regulates what? - ANSWER: Internal Organs, keeping the
bodys internal environment in a relatively constant state (homeostasis)
Sympathetic System - ANSWER: 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.
Parasympathetic System - ANSWER: Maintains the resting or vegetative state and
tends to slow processes on various organs. "Couch potato states"
What drugs depress the vital centers, resulting in hypotension and respiratory
depression? - ANSWER: Barbiturates and propofol
What drugs stimulates the vital centers and causes inscrease in blood pressure and
pulse? - ANSWER: Ketamine
Superior vena cava - ANSWER: Above the heart the blood is returned
Inferior vena cava - ANSWER: Below the heart the blood is returned
Coronary Sinus - ANSWER: a wide venous channel about 2.25 centimeters in length
that receives blood from the coronary veins and empties into the RIGHT atrium
Arteries - ANSWER: All vessels leading away from the heart
