Anatomy
two bones of the upper jaw
Maxillae
tubular, elastic, THICK-walled branching vessels that carry OXYGENATED blood away from the heart through the body.
Artieries
Muscles respond to conscious commands
Voluntary / Striated
Carry messages to the brain and spinal cord
Sensory or afferent nerves
The study of the functions of these organs and systems
Physiology
two bones that form the upper cheek and the bottom of the eye socket
Zygomatic
tublular, elastic, THIN-walled branching vessels that carry OXYGEN-DEPLETED blood from the capillaries to the heart.
Veins
Muscles respond automatically to control various body functions, including the internal organs
Involuntary / Non-striated
Carry messages form the brain to the muscles.
Motor or efferent nerves
Basic units of life
Cells
Portion of the muscle joined to movable attachments: bones, movable muscles or skin.
Insertion
Small vessels that take nutrients and oxygen form the arteries to the cells and take waste products form the cells to the veins
Capillaries
Muscles separate the fingers
Abductor
What does the 6th cranial nerve do?
Abducent
The production department. Most of the chemical activities within the cell
Cytoplasm
What is the composition of a bone?
2/3 Mineral matter, 1/3 Organic matter
All blood from the head, face and neck returns through two veins
Internal (IJV) and External (EJV) Jugular Veins
Muscles draw the fingers together
Adductor
Extends to the lower eyelid, side of the nose, upper lip and mouth
Infraorbital Nerve
Colorless gel-like substance that contains water, salt and nutrients obtained from food.

Ethmoid
Blood travels through the pulmonary artery to the lungs where it is oxygenated. This process is called..
Pulmonary arteries
mid-forearm, on the outside of the arm. This muscle straightens the fingers and wrist
Extensor Radialis
Regulates motor function, muscle movement and balance.
