A&P Unit 1 (Human Body) Test Flashcards
definition “Anatomy”
structure / form
definition “Physiology”
function / how something works
body plane: “Sagittal”
divides body into right left portions
body plane: “Coronal”
divides body into anterior and posterior portions
body plane: “Mid-sagittal”
divides body into equal right and left portions
superior/cephalic
one part being above the other / towards the head
inferior/caudal
a part being located below another part / towards the feet
anterior/ventral
a part being towards the front / towards the belly
posterior/dorsal
part being behind another / towards the back
medial
closer to the midline than another structure
lateral
farther from midline than another structure
bilateral
paired structures on both sides
ipsilateral
located on same side of midline of body
contralateral
located on opposite side of midline
proximal
located closer to trunk / point of origin
distal
located further from trunk / point of origin
superficial
located towards surface of body
peripheral
located away from body or another structure
Body Planes are…
imaginary plates that divide the body into portions
Membrane that lines organ is visceral or parietal?
organ = visceral
Membrane that lines box of serous cavity parietal or visceral?
cavity = parietal membrane
apendicular region of the body consists of and is responsible for?
upper and lower limbs / manipulation of environment & movement / no vital organs
axial region consists of
head / trunk / responsible for
The pelvis is
bowl-shaped pelvis protects and supports internal organs
2 gross body cavities are?
Dorsal body cavity (central nervous, trunk, head) / ventral body cavity (anterior aspect of trunk, organs (viscera)
thoracic cavity consists of
superior / anterior portion of trunk
Mediastinum of thoraic
separates pleural cavities of thoracic cavity into halves
Abdomino pelvic cavity
occupies inferior anterior portion of trunk
lined with peritoneum membrane
cranial cavity houses?
brains subdivision of dorsal body cavity
spinal (vertebral) cavity
houses the spine, subdivision of dorsal body cavity
4 types of tissues
- Epithelial
- Connective
- Nervous
- Muscle
define tissue
group of similar cells that work together to perform a particular function
The cell is….
the most basic and functional structural unit of a living organism
3 common structures of cell
cell membrane, cytosol (cytoplasm), nucleus
cell membrane
phospholipid bilayer, allows lipid soluble substances to pass while preventing entrance of water, outer layer
cytoplasm
inside membrane, outside nutrients, contains organelles
ribosomes
responsible for protein synthesis
mitochondria
powerhouse of cell, aerobic respiration, generates atp
