Chapter 4 - Body Structure Flashcards
what are a cell’s main activities?
utilizing food, facilitating reproduction, and eliminating waste products
what are a cell’s three main structures
cell membrane, cytoplasm, nucleus
cytology
the study of the body at the cellular level
cell membrane function
acts as a barrier that supports and protects the intracellular contents
what is cytoplasm made up of
jellylike matrix of proteins, salts, water, dissolved gases, and nurtients
nucleus functions
responsible for metabolism, growth, reproduction, carries deoxyribonucleic acid (DNA)
histology
study of tissues
covers surfaces of organs, lines cavities, and canals, forms tubes, and ducts, provides the secreting portions of lands, and makes up the outer layer of the skin. composed of cells arranged in a continuous sheet consisting of one or more layers.
epithelial tissue
supports and connects other body tissues, various types such as cartilage, adipose, one, elastic fiber, and even blood
connective tissue
provides the contractile tissue of the body, which is responsible for movement
muscle tissue
transmits electrical impulses as it relays information throughout the entire body.
nervous tissue
what is a plane
an imaginary flat surface that divides the body into two sections
divides body into an anterior and posterior sections
coronal (frontal) plane
divides the body into top and bottom sections
transverse (horizontal) plane
divides the body into right and left halves
midsagittal (median) plane
abduction
movement away from the misdagittal plane of the body or one of its parts
adduction
movement toward the midsagittal plane of the body
medial
pertaining to the midline of the body or structure
lateral
pertaining to a side
superior (cephalad)
toward the head or upper portion of a sturcture
inferior (caudal)
away from the head or structure
proximal
nearer to the center of to the point of attachment to the body
distal
further from the cener or from the point of attachment to the body
anterior (ventral)
front of the body
posterior (dorsal)
back of the body
parietal
pertaining to the outer wall of the body cavity
visceral
pertaining to the viscera, or internal organs, especially the abdominal orgains
prone
lying on the abdomen, face down
supine
lying horizontally on the back, face up
inversion
turning inward of inside out
eversion
turning outward
palmar
pertaining to the palm of the hand
plantar
pertaining ot the sole of the foot
superficial
toward the surface of the body (external)
deep
away from the surface of the body (internal)
what is a body cavity
are spaces within the body that hold, protect, separate, and support internal organs.
a cavity that is located on the back of the body
dorsal cavity
the cavity located on the front of the body
ventral cavity
part of the dorsal cavity that is formed by the skull and contains the brain
cranial cavity
part of the dorsal cavity that is formed by the backbone, contains the spinal cord
spinal cavity
membranes that line dorsal cavities
meninges
part of the ventral cavity that contains the lungs and heart
thoracic cavity
the cavity that is part of the ventral cavity but is split into the abdominal cavity and pelvic cavity
abdominopelvic cavity
cavity (part of the abdominopelvic cavity) that contains the liver, stomach, intestines, and kidneys
abdominal cavity
cavity (part of the abdominopelvic cavity) that contains that urinary bladder, reproductive organs, and uterus or prostate gland
pelvic cavity
what is the abdominopelvic cavity divided into, two imaginary lines that form a cross in the midsection of the lower torso?
4 quadrants
right lobe of the liver, the gallbladder, part of the pancreas, and part of the small and large intesitnes
RUQ
left lobe of the liver, the stomach, the spleen, part of the pancreas, and part of the small and large intestines
LUQ
part of the small and large intesitnes, the appendix, the right ovary, the right fallopian tube, and the right ureter
RLQ
part of the small and large intestines, the left ovary, the left fallopian tube, and the left ureter
LLQ
the abdominopelvic cavity can be divided into, used to identify the location of underlying body structures and visceral organs
nine regions
upper right lateral region beneath the ribs
right hypocondriac
upper middle region
epigastric
upper left lateral region beneath the ribs
left hypochondriac
