Exocrine gland

endocrine gland

glands

secrete substances for elimination or for use elsewhere in body

organs with mixed glands (exocrine and endocrine)

liver, gonads (ovaries and testes), pancreas

holocrine gland

sebaceous glands

serous glands

mucous glands

mixed glands

cytogenic glands

release whole cells—sperm and eggs

merocrine glands

release product by exocytosis;

apocrine glands

cutaneous membrane

skin

mucous membrane

lines passageways that open to the exterior, such as the respuratory, digestive, urinary, and productive tracts. often covered with mucous by goblet cells

synovial membrane

serous membrane

components of a membrane

epithelium, lamina propria, and connective tissue

hyperplasia

hypertrophy

neoplasia

differentiation

metaplasia

changing from one type of mature tissue to another—vagina goes from simple cuboidal tissue before puberty to stratifies squamous after

atrophy

shrinkage from loss of cell size/number (leg in cast muscle example)

necrosis

apoptosis

programmed cell death

viscera

internal organs of the body

dense regular connective tissue

dense irregular connective tissue

adipose tissue (adipocytes)

hyaline cartilage

clear glass matrix, chondrocytes in small clumps within lacunae “little lake,” over ends of bones and moveable joints, supportive material in larynx, trachea, bronchi, and fetal skeleton

elastic cartilage

fibrocartilage

areolar tissue

connective tissue; main cell is fibroblast, contains collegen and elastic fibers and lots of ground substance, underlines all epithelia and creates passageway for nerves and blood vessels,

reticular tissue

connective tissue; loose network of reticular fibers and cells
