Anatomy pt1 Flashcards
Appendix
Small tubular structure attached to lower border of the cecum in lower right quad of abdomen
Appendicular skeleton
Arms legs pelvis n shoulder girdle
Arterioles
Smallest branches of arteries leading to vast network of capillaries
Atrium
One of two upper chambers of heart
Automatic nervous system
Part of nervous system that regulates functions like sweating n digestion. Not controlled voluntarily
Axial skeleton
Skull, spinal column, n rib cage
Ball and socket joint
Joint that allows internal n external rotation as well as bending
Beta-adrenergic receptors
Portions of nervous system that can increase force of contraction if the heart, increase heart rate n bronchial dilation
Biceps
Large muscle that covers humerus
Bilateral
Appears on both sides
Bile ducts
Ducts that convey bile between liver n intestine
Bloop pressure
Pressure that blood exerts against walls of arteries as it passes thru
Brachial artery
Major blood vessel in upper extremity that supplies blood
Brain
Controlling organ of the body
Brain stem
Area between spinal cord a cerebrum, surrounded by cerebellum. Controls functions necessary for life life respiration
Capillary vessels
Tiny blood vessels between Arterioles n venues that permit transfer if oxygen, co2, nutrients, n waster between body tissues n blood.
Cardiac muscle
Heart muscle
Carotid artery
Major artery that supplies blood to head n brain
Cartilage
Support structure of skeletal system that provides cushioning between bones.
Cecum
First part of large intestine into which the ileum opens
Central nervous system
Brain n spinal cord
Cerebellum
“Little brain”. Coordinates various activities of the brain, particularly fine body movements.
Cerebrospinal fluid
Fluid produced in ventricles of brain that flows into subarachnoid space n bathes the meninges
Cerebrum
“Grey matter” Largest part of three subdivisions of brain. Controls movement, hearing, balance, speech, visual perception, emotions n personality
Cervical spine
First seven vertebrae that lie on neck.
Chordae tendineae
Thin bands of fibrous tissue attached to valves in heart n prevent them from inverting.
Chyme
Substance that leaves stomach. Combo of eaten foods n stomach acids
Circulatory system
Moves blood, oxygen, nutrients, co2, n cellular waste throughout body
Clavicle
Collarbone
Coccyx
Last 3 or 4 vertebrae of spine. Tailbone
Coronal plane
Cuts body into front n back parts
Cranium
Area of head above ears n eyes. Skull.
Cricoid cartridge
Firm ridge of cartridge that forms lower part of larynx
Cricothyroid membrane
Thin sheep of fascia that connects thyroid n cricoid cartilages that make up larynx
Dead space
Any portion if airway that does not contain air n can’t participate in gas exchange such as trachea n bronchi.
Dermis
Inner layer of skin containing hair follicles, sweat glands, nerve endings, n blood vessels
Diastole
Relaxation or period of relaxation of heart, especially the ventricles
Diaphragm
Muscular dome that forms undersurface of throat, separating chest from abs. Contraction if the diaphragm brings air into lungs. Relation expels air.
Diffusion
Gas moves from higher to lower concentration
Distal
Further from trunk or closer to end of extremity
Dorsal
Posterior
