Anatomical Terms Flashcards
arcade
how teeth are arranged
lingual surface
surface of teeth touching tongue
palatal surface
tooth surface of maxilla that touches tongue
buccal/vestibular surface
aspect of teeth touching cheeks
occlusal surface
aspect of teeth that meets when chewing
labial surface
tooth surfacing facing lips
contact surfaces
aspect of tooth that touch other teeth
- mesial: aspect closest to midline of dental arcade
- distal: furthest from midline
cavity
hollow space in the body that contains organs
peritoneum
membrane lining walls of abdominal and pelvic cavities
- parietal: outer layer lining cavities
- visceral: inner layer surrounding organs
peritonitis
inflammation of the peritoneum
umbilicus
pit in the abdominal wall where the umbilical cord was
mesentery
layer of peritoneum that suspends parts of the intestines in the abdominal cavity
retroperitoneal
superficial to the peritoneum
dorsal recumbency
lying on back
AKA supine
ventral/sternal recumbency
lying on belly
AKA prone
adduction
movement towards midline
abduction
movement away from midline
flexion
closure of a joint (flexing bicep)
extension
straightening a joint
supination
rotating limb so palmar surface is turned upward
pronation
rotating the limb so the palmar surface is turned downward
protoplasm
cell membrane + cytoplasm + nucleus
cell membrane
lining of cells
cytoplasm
gelatinous material in membrane that is not part of the nucleus
- organelles are found here
nucleus
contains nucleoplasm, chromosomes
nuceloplasm
material in nucleus
chromosomes
DNA in nucleus
congenital
present at birth
tissue
group of cells similar in structure and function
epithelial tissue
covers internal and external surfaces
endothelium
epithelium of internal organs
mesothelium
epithelium of serous membranes
connective tissue
support and structure
muscle tissue
cells that can contract and relax
nervous tissue
cells that can react and send impulses
anaplasia
change in structure of cells and their orientation
aplasia
lack of development of organ/tissue/cell
dysplasia
abnormal growth of organ/tissue/cell
hyperplasia
abnormal increase in cells
hypoplasia
incomplete development of organ/tissue/cells
neoplasia
new uncontrolled growth of cells (forms tumours = mass of tissue)
benign
not recurring
malignant
spreading
atrophy
decrease in size
dystrophy
defective growth in organ/tissue/cell
hypertrophy
increase in size of organ/tissue/cell
glands
groups of cells that secrete
exocrine gland
secrete outside of body via ducts
endocrine gland
secrete directly into blood, no ducts
