Anatomy and Physiology Flashcards
Abductor
muscles that draw a body part such as fingers, arms, or toe away from the midline. Separates fingers
Adductors
muscles that draw the body parts inward or toward the midline. Draw fingers together.
Adipose Tissue
a specialized connective tissue considered fat which gives smoothness and contour to the body and cushions and insulated the body.
Anatomy
study of the human body that can be seen with the naked eye.
Anabolism
constructive metabolism. Building larger molecules from smaller ones.
Angular Artery
artery that supplies blood to the side of the nose
Anterior Auricular Artery
supplies blood to the front of the ear
Aorta
largest artery, arterial trunk that carries blood from the heart to be distributed by branch arteries through out the body
Arteries
thick walled muscular and flexible tubes that carry oxygenated blood
Arterioles
small arteries that deliver blood to capillaries
Autonomic Nervous System (ANS)
part of the nervous system that controls the involuntary muscles, regulates the action of the smooth muscles, heart glands and blood vessels
Belly (of muscle)
center point of muscle
Bicep
muscle producing the contuor of the front and inner side of the upper arm
Blood
nutritive fluid circulating though the circulatory system
Blood Vessels
tube like structure that transport blood to and from the heart nd to various tissues of the body
Body System
groups of bodily organs acting together to perform one or more functions (11 systems in body)
Brain
part of the central nervous system contained in the cranium, largest and most complex nerve tissue. controls all body functions
Buccal nerve
nerve that affects muscles of the mouth
Buccinator
thin flat muscle of the cheek between the upper and lower jaw that compresses the cheeks and expels that air between the lips
Capillaries
tiny thin walled blood vessels that connect the smaller arteries to the veins
Catabolism
phase of metabolism that involves the breaking down of complex compounds within the cells into smaller ones
Cell membrane
part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell
Cells
basic unit of all living things.
Central Nervous System (CNS)
consist of the brain, spinal cord, spinal nerves and cranial nervess
Cervical Nerves
nerves that originate at the spinal cord, whose branches supply the muscles and scalp at the back of the head
Cervical Vertebrae
seven bones of the top part of the vertebral column
Clavicle
“Collarbone” Bone joining the sternum and scapula
Common Carotid artery
arteries that supply blood to the face and head
Connective Tissue
fibrous tissue that binds together protects and supports the various parts of the body such as bone cartilage and tendons
Corrugator
facial muscle that draws eyebrows down and wrinkles the forehead vertiically
Cytoplasm
all the protoplasm of a cell that excepts that which is in the nucleus, contains food material necessary for cell growth.
Deltoid
large triangular muscle covering the shoulder joint that allows the arms to extend outward and to the side of the body
Depressor Labii Inferioris
muscle surrounding the lower lip that depresses the lower lip and draws it to one side.
Digestive system
responsible for changing food into nutrients and waste
Digestive enzymes
chemicals that change certain kinds of food into a form that can be used by the body
Digital Nerve
sensory motor nerve that with its branches supplies impulses to the fingers
11th Cranial Nerve
“acessory” nerve. motor nerve that controls the motions of the neck and shoulder muscles
Endocrine glands
ductless glands. releases secretions called hormones directly into the bloodstream
Endocrine system
group of specialized glands that affect the growth development, sexual activities and health of the entire body
Epicardial Aponeurosis
tendon connecting the occipitalis and the frontalis
Epicarnius
the broad muscle that covers the top of thee skill and consists of the occipitalis and frontalis
Extensor
muscles that straighten the wrist hand and fingers to form a straight line
External carotid artery
artery that supplies blood the the anterior parts of the scalp, ear, face, neck and sides of the head
External Jugular vein
vein located on the side off the neck that carries blood returning to the heart from the head face and neck
Facial Artery
supplies blood to the lower region of the face mouth and nose
5th cranial nerve
“trifacial” Cheif of sensory nerve of the face, serves as the motor nerve of the muscles that control chewing
Flexors
extensor muscles of the wrist involved in flexing the wrist
Frontal Artery
artery the supplies blood to the forehead and eyelids
Frontal Bone
forms the forehead
Frontalis
Anterior portion of the epicranius, muscle of the scalp that raises the eyebrows, draws the scalp forward and causes wrinkles across the forehead
Gastrocnemius
located with the soleus in the posterior (back) compartment of the leg.
Glands
specialized organs that remove certain elements from the blood to convert them into new compounds
Heart
cone shaped organs that keeps blood moving within the circulatory system
Hormones
secretions produced by one of the endocrine glands and carried by the bloodstream to another part of the body
Humerus
uppermost and largest bone in the arm
Hyoid bone
U-shaped bone at the base of the tongue that supports tongue muscle
inferior labial artery
supplies blood to lower lip
Infraorbital artery
originates from the internal maxillary artery and supplies blood the the eye
