A | B |
blood | c.t. --transports material |
adipose | c.t. -- stores fat |
cartilage & elastic tissue | c. t.-- strengthens & connects structures e.g.ligaments |
mesentary | c. t.--connects abdominal organs to coelom |
bone | c. t.--osteocytes secrete Ca minerals; supports, allows locomotion |
connective tissue (c.t.) | mesodermal cells surrounded by copious extracellular matrix |
Connects, supports, strengthens, stores, transports | functions of c.t. |
organ | several tissues connected & interacting |
organ systems | group of organs cooperating |
muscle tissue (m.t.) | mesodermal cells which contract by sliding myosin & actin filaments |
smooth muscle | involuntary autonomic NS causes contractions; in organs, blood vessels; no straitions |
skeletal muscle | ; voluntary somatic ns controlled multinucleate fibers w/ striations--many sarcomeres |
cardiac muscle | striated branching fibers in heart; autonomic ns control |
epithelial tissue (e.t.) | ecto- or endodermal cells; cover, line, protect, or secrete |
nervous tissue (n.t.) | ectodermal cells--neurons, neurosecretory cells, glia; relay sensory info, control muscles & glands |
squamous e.t. | sheets of near rectangular cells; e.g., surface skin |
ciliated columnar e.t. | column-like w/ cilia at organ lining surfaces, increasing absorption (sm intestine) or moving materials (respiratory & fallopian tube linings |
cuboidal e.t. | cube shaped cells forming sheets, e.g., capillaries walls |
stratified e.t. | differently shaped epithelial cells in distinct layers |
tissue | similar specialized cells connected & cooperating for a common function. |
