Anatomy pt3 Flashcards
liver
large solid organ that lies in right upper quadrant immediately below diaphragm; produces bile, stores glucose, and produces many substance that help regulate immune responses.
lumbar spine
lower back, lowest 5 unfused vertebrae
mandible
bone of lower jaw
manubrium
upper quarter of sternum
maxillae
upper jawbones that assist in formation of orbit, nasal cavity, and palate. holds upper teeth
medial
closer to midline
medulla oblongata
nerve tissue that is continuous inferiorly with spinal cord; serves as conduction pathway for ascending and descending nerve tracts; coordinates heart rate, blood vessel diameter, breathing, swallowing, vomiting, coughing, n sneezing.
midbrain
responsible for helping to regular level of consciousness
midsagittal plane (midline)
from middle of forehead to floor
minute volume
amount of air that moves in and out of lungs per minute minus dead space.
motor nerves
carry info from central nervous system to muscles
mucous membranes
lining of body cavities and passages that communicate directly or indirectly with environment outside body
mucus
opaque, sticky secretion of the mucus membranes that lubricate body openings.
musculoskeletal system
bones n voluntary muscles of body
myocardium
heart muscle
nasopharynx
part of pharynx that lies above roof of mouth
nervous system
controls all activities of body
norepinephrine
neurotransmitter n drug used to treat shock; produces vasoconstriction through its alpha-stimulator properties
occiput
most postier portion of cranium
oncotic pressure
pressure of water to move into capillary, as the result of presence of plasma proteins
orbit
eye socket; made up of maxilla and zygoma
oropharynx
tubular structure that extends vertically from back of mouth to esophagus and trachea
ovaries
female glads that produce sex hormones and ova(eggs)
palmar
forward facing part of hand in anatomic position
pancreas
flat, solid organ that lies below liver and stomach; major source of digestive enzymes and produces insulin
parasympathetic nervous system
in control of involuntary vegetative functions
parietal regions
areas between temporal and occipital regions of cranium
patella
kneecap
pathophysiology
study of how normal physiologic processes are affected by disease
perfusion
circulation of oxygenated blood within an organ or tissue in adequate amounts to meet cells’ current needs
peripheral nervous system
consists of 31 pairs of spinal nerves and 12 pairs of cranial nerves. can be sensory, motor, or connecting nerves
peristalsis
wavelike contraction of smooth muscle by which ureters or other tubular organs propel their contents.
plantar
bottom of foot
plasma
sticky, yellow fluid that carries blood cells n nutrients and transports cellular waste material to organs of excretion.
platelets
tiny, disk-shaped elects that are much smaller than cells; essential in initial formation of a blood clot
pleura
serous membranes covering the lungs n lining thoracic cavity, completely enclosing the pleural space
pleural space
potential space between parietal pleura and visceral pleura. under “normal conditions” it don’t exist
pneumotaxic (pontine) center
portion of pons that assists in creating shorter faster respirations
pons
organ that lies below midbrain and above medulla and contains numerous important nerve fibers used for sleep, respiration, n medullary respiratory center
posterior
back
posterior tibial artery
artery just behind the medial malleolus; supplies blood to foot
