Chapter 4 Flashcards
Epithelial tissue
covers body surfaces, lines body cavities & hollow organs & ducts, forms glands
Connective tissue
protects and supports the body and organs, binds organs together, stores energy reserves as fat, provides immunity
Muscular tissue
generate physical force needed to make body move
Nervous tissue
detects changes and responds to them
Functions of simple squamous
filtration, diffusion, osmosis, secretion in serous membranes
Location of simple squamous
heart, blood & lymphatic vessels, air sacs of lungs, capsul of kidneys, tympanic membrane, serous membranes
Functions of simple cuboidal
secretion, absorption
Location of simple cuboidal
kidney tubules, ducts of glands, surface of ovary, capsule of lens of eye
Functions of ciliated simple columnar
secretion (mucus) that traps foreign particles
Location of ciliated simple columnar
line upper respiratory , fallopian tubes, uterus
Functions of pseudostratified columnar
secretion (mucus) that traps foreign particles
Location of pseudostratified columnar
lines upper respiratory
Functions of stratified squamous
protection
Location of stratified squamous
superficial layer of skin, lines wet surfaces, covers tongue
Functions of stratified cuboidal
protection, limited secretion, absorption
Location of stratified cuboidal
ducts of apocrine glands & esophageal glands, male urethra
Functions of stratified columnar
protection and secretion
Location of stratified columnar
urethre, ducts of some glands, conjunctiva of eye
Functions of transitional
allow stretch and maintain protection while holding large amounts of fluid without breaking
Location of transitional
urinary bladder, ureters, urethra
What is a gland?
single or group of epithelial cells adapted for secretion
What are the cells involved in connective tissue?
fibroblasts, macrophages, palsma cells, mast cells
ground substance
supports and binds cells together, provides medium for exchange of materials
fibers
provide strength and support, three types: collagen, elastic, reticular
Functions of areolar
strength, elasticity, support
Location of areolar
deep subcutaneous, superficial dermis, mucous membrane, blood vessel, nerves, body organs
Functions of adipose
reduce heat loss through skin, energy reserve, supports & protect organs
Location of adipose
deep subcutaneous, around heart and kidneys, yellow bone marrow, padding joints
Functions of reticular
stroma of organs, binds smooth muscle cells, filters worm out blood cells
Location of reticular
liver, spleen, lymph nodes, red bone marrow, blood vessels, muscles
Functions of dense regular
strong attachment between structures, resist tension
Location of dense regular
tendons, ligaments
Functions of dense irregular
provides pulling strength in many directions
Location of dense irregular
deep dermis, around bone & cartilage & muscle, heart valves, capsules around organs, beneath skin
Functions of hyaline cartilage
provides smooth surface for movement at joints, flexity, support
Location of hyaline cartilage
ends of long bones, anterior of ribs, nose, laryns, trachea, bronchi, bronchial tubes, embryonic, fetal skeleton
Functions of fibrocartilage
support & join structures, strength, rigidity
Location of fibrocartilage
hip bones, discs between vertebrae, knee, tendons that join into cartilage
Functions of elastic
strength & elasticity, maintains shape of certain structures
Location of elastic
top of larynx, external ear, auditory tubes
Types of epithelial membrances
mucous, serous, synovial
Mucous membrane
line cavities that open to exterior
Serous membrane
line closed cavities, cover organs in cavities
Synovial membrane
line joint cavities, bursae, tendon sheaths
fibrosis
formation of scar tissue
