large particles are trapped in a portion of the plasma membrane & brought into the cell, cell eating
phagocytosis
cell products move out of a cell through the cell membrane
exocytosis
a cell’s shape is determined by its __
function
process in which fluid is brought into the cell, cell drinking
pinocytosis
the body’s largest membrane
cutaneous membrane
secretes fluid that prevents friction as the lungs expand
serous membrane
bone cells
osteocytes
lines body cavities
epithelial tissue
which cells can develop into many different cell types?
stem cells
what is the main difference between exocrine & endocrine glands?
exocrine glands secrete substances in to ducts, & endocrine glands secrete substance into the bloodstream
what do membranes do?
line body cavities, cover body surfaces, & separate organs
TRUE OR FALSE: the primary purpose of serous membranes is to secrete serous fluid, which reduces friction as organs, especially the heart & lungs, expand & contract. mucous membranes secrete mucus; they also line body surfaces exposed to the outside environment. cutaneous membranes cover the exterior surface of the body.
true
TRUE OR FALSE: cartilage heals quickly because of its rich blood supply
false, cartilage does not have a blood supply, therefore it heals slowly
which of the following muscle types is under voluntary control?
skeletal
what is the most abundant & varied tissue in the body with a structure very different than epithelia tissue?
connective
which type of tissue allows for rapid communication between various parts of the body?
nervous
this type of muscle tissue has the function of heart contractions:
cardiac
this type of membrane lines body cavities & covers internal organs
serous
protects the nucleus from sun damage
melanin
secretes sweat
eccrine
outer most layer of the skin
epidermis
inner layer of the skin
dermis
pallor
pale skin
yellow discoloration of the skin
jaundice
blue tint to the skin
cyanosis
abnormal redness to the skin
erythema
hematoma
bluish, black or yellowish mark on the skin
extremely pale skin, white eyes & pink eyes
albinism
most common type of skin cancer, least dangerous
basal cell carcinoma
slow growing, may metastasize, has a red scaly appearance
squamous cell carcinoma
most deadly of all skin cancers
malignant melanoma
clubbing of the nail is a sign of
lung disease
a burn that only involves the epidermis is classified as
first degree
allergic reaction resulting in multiple red patches (wheals) that are intensely itchy
urticaria
recurring skin disorder characterized by red papule & scaly silvery plaques
psoriasis
inflammation of the sebaceous glands, especially during puberty
acne
fungal infection of the skin
tinea
contagious bacterial infection usually caused by strep or staphylococci
impetigo
inflammation of the skin characterized by itching redness, often the result of exposure to an irritant
dermatitis
the central, shaft like portion of a long bone is called the
diaphysis
the medullary cavity in most adults is filled with
yellow bone marrow
which substance covers the surface of the epiphysis of a long bone
articular cartilage
TRUE OR FALSE: the epiphyseal plate consists of a layer of hyaline cartilage & is the site of bone lengthening
true
which type of fracture is most likely to occur in a car accident?
comminuted
which type of fracture is most likely to occur in young children?
greenstick
which classification of bone protects organs or provides a large surface area for the attachment of muscles?
flat bones
the condition in which bones lose so much mass they become extremely brittle is called __?
osteoporosis
a fracture in a diseased or weakened bone, usually the result of a force that would not fracture a healthy bone is call a __ fracture
pathologic
