| Question | Answer |
|---|---|
| Epithelial Tissue | large sheets of cells covering all body surfaces and lining the outside of organs |
| Epithelial Tissue | Covering & lining epithelia and Glandular epithelia |
| Covering & Lining epithelia | on external and internal surfaces (ex: skin) |
| Glandular epithelia | secretory tissue in glands (ex: salivary glands) |
| Cell Junctions' goal | to glue cell tg to prevent shedding |
| Tight Junctions | extremely strong; don't allow exchange |
| Gap Junctions | has a door for passage for exchange of materials; extremely weak |
| Desmosome | strong; allow certain materials exchanged |
| Desmosome | connect epithelial cells on skin; ex: GI tract |
| Loose CT types | Areolar, Adipose, Reticular |
| Reticular Loose CT | structural framework; ex: liver & spleen |
| Dense CT types | Regular & Irregular |
| Regular DCT | movements in one direction |
| Irregular tissue | allow stretching in multiple directions |
| Loose CT | spaces between components & CT |
| Dense | limited/ no space |
| CT cells | Mesenchymal, Fibroblasts, Adipocytes, & Macrophages |
| Mesenchymal Cell | main type; mother cell; responsible for making CT |
| Fibroblasts | produce fibers |
| Adipocytes | fat cells |
| Macrophages | kill bacteria, clean debris; immune cells |
| Matrix | medium where cell and fibers live w/in |
| Matrix | make up of protein & sugars |
| Collagen Fibers | thick and provide tensile strength; overtime they will become loose |
| Elastic Fibers | allow stretching; allow tissue to return its original stretch; ex: aorta |
| Reticular Fibers | structural support; framework |
| Muscle Tissue | excitable & contractile |
| Excitable | respond to a stimulus |
| Contractile | can shorted & generate a pulling force |
| Skeletal muscle appearance | Cylinder & elongated; straited |
| Skeletal muscle # of nucleus | multinucleated |
| Skeletal muscle control | voluntary |
| Skeletal muscle location | around bones |
| Skeletal muscle functions | body movement |
| Cardiac muscle appearance | rectangular and straited; branched |
| Cardiac muscle control | voluntary |
| Cardiac muscle location | heart |
| Cardiac muscle functions | blood movement |
| Cardiac muscle | intercalated disc strong attachment between cells |
| Smooth muscle appearance | spindle shape and non-straited |
| Smooth muscle control | involuntary |
| Smooth muscle location | walls of hollow organs (stomach, blood, vessels, intestines, etc.) |
| serous membrane | pleura cover lungs |
| mucous membrane | line the inner body cavities; immune function; anything that comes from outside of body |
| apical surface | usually opens in a space |
| basal surface | usually touches the connective tissue |
| polarity | certain organelles are always down & certain organelles are always up. |
| simple squamous epithelium | flattened & thin; gas exchange |
| stratified (multiple layers) squamous epithelium | epidermis; protection; ex: skin & tongue |
| Simple cuboidal epithelium | box-like; active in secretion and absorption of molecules; found in glands & kidney; help in secretion |
| Simple columnar epithelium | found in intestines, tall; absorption & secretion of molecules; forms the lining of some sections of the GI system; located in the basal end of cells |
| Pseudostratified columnar epithelium | false stratified; diff positions at all times; found in trachea, reproductive tracts, & ureters |
| Transitional epithelial tissue | cell changes shapes; ex: bladder |
| Glandular Epithelia | exocrine & endocrine |
| Cartilage | chondrocyte |
| Lacunae | space cartilages occupy |
| Hyaline | a type of cartilage; glass-like strong & flexible CTs; in rib cages & bone ends |
| Hyaline | strong under pressure; most common; short & dispersed collagen fibers |
| Elastic Cartilage | rigid support & elasticity, weaker under pressure; in nose & ear |
| Fibrocartilage | strongest under pressure; run in bundles; in knee joints & intervertebral discs |
| Tissue types | epithelial, connective, muscle, & nervous tissue |
| Epithelial tissue | protection, absorption, filtration, excretion, secretion, & sensory reception |
| Epithelium cells | gatekeepers of body; allowing selective transfer of materials across a physical barrier |
| Basal lamina | a mix of glycoproteins & collage; attached to basement membrane provided by CT |
| Epithelial Tissue | avascular, generation |
| Endocrine gland | secrete in the area around that will diffuse through the blood; ex: thymus, adrenal cortex, & gonads |
| Exocrine gland | secrete into a duct "sewer system" |
| Matrix | # amounts of ground substance |
| CT | cells, matrix, & protein fibers |
| Fibroblasts | most abundant cell in CT proper; responsible for the extra-cellular matrix |
| Mesenchymal cell | can differentiate into any type of CT needed for repair and healing of damaged tissue |
| Cartilage | avascular Ct that contain polysaccharides called chondroitin sulfates |
| Bone (Osseous) | hardest CT; provides protection to internal organs & body support |
| Blood & Lymph | fluid CT; transport nutrients, salts, & wasted throughout the body |
| Intercalated discs | specialized cell junctions |
| Contraction | responsible for involuntary movements in the internal organs |
| Nervous Tissue | Neuron & Neuroglia |
| Cutaneous Membrane | Epithelia membrane; ex: skin |
| Cutaneous Membrane | stratified squamous epithelial membrane resting on top of CT |
| Mucous Membrane | made of CT & epithelia tissue; line the body cavities & hollow passageways that open to the external environment. |
| Serous Membrane | Epithelial membrane that is supported by CT; line the cavities that don't open to the outside |
| Stratified squamous ET | found in areas of high friction and causes areas to become thicker to protect from damage |
| Pseudo-stratified columnar | lining the small & large intestine & designed to absorb nutrients into the blood steam & create mucous to lubricate the digestive tract. |
| Skeletal tissue location | attached to bones/skin |
| Stratified squamous ET location | mouth/vagina, epidermis |
| Adipose loose CTP location | breasts abdomen, eyes, & kidneys |
| Areolar loose CTP function | wrap/cushions organs, inflame |
| Elastic cartilage location | External Ear, Epiglottis |
| simple squamous ET function | secretes lubrication in serosae |
| simple squamous ET location | serosae, air sacs, heart lining |
| simple cuboidal ET location | kidney tubules, ovary surface |
| irregular dense CTP location | skin dermis, joints, d-tract |
| reticular loose CTP location | lymphoid orangs (spleen, marrow) |
| regular dense CTP location | tendons, ex: ligaments |
