organelle function and location Flashcards
ribosome
site of protein synthesis
smooth ER
site of lipid synthesis
mitochondria
main site of ATP synthesis
nucleus
encloses chromatin
golgi apparatus
packages protein for transportation
lysosome
sac of digestive enzymes
centriole
form basal bodies; help direct mitotic spindle formation
cytoskeleton
internal cellular network of rodlike structures
inclusion
ex: glycogen granules, foreign ingested material
plasma membrane
forms external boundary of cell
nucleolus
packaging site for ribosomes
lines body cavities and covers body’s external surfaces
Epithelium
pumps blood, flushes urine out of body, allows one to swing a bat
Muscle
forms endocrine and exocrine glands
Epithelium
anchors, packages, and supports body organs
Connective
classified based on shape and arrangement of cells
Epithelium
derived from mesenchyme
Connective
major function is to contract
Muscle
transmits electrical signals
Nervous
consists of cells within an extracellular matrix
Connective
most widespread tissue in the body
Connective
forms nerves and the brain
Nervous
attaches bone to bones and bone to muscles
dense regular connective tissue
insulates against heat loss
adipose connective tissue
forms fibrous joint capsule
dense irregular connective tissue
makes up intervertebral discs
fibrocartilage
composes basement membrane
(soft packaging tissue with jelly-like matrix)
areolar connective tissue
forms the larynx, costal cartilages of ribs, and embryonic skeleton
hyaline cartilage
provides flexible framework for external ear
elastic cartilage
provides levers for muscles to act on
osseous tissue
forms walls of large arteries
elastic connective tissue
Skeletal muscle is:
Striated
Cylindrical cells
Voluntary
Many nuclei
Attached to bones
Cardiac muscle is:
Striated
Branching cells
Involuntary
One nucleus
Intercalated discs
Forms heart walls
Smooth muscle is:
Spindle-shaped cells
Involuntary
One nucleus
In wall of bladder and stomach
