QuestionAnswer
what are the 4 major types of tissue? Epithelial, Connective, Muscle, Nervous
Cells that are tightly packed with little extracellular matrix Epithelial
What tissue binds, supports, and protects other tissues and organs? Connective
This tissue may be spindle-shaped, branching or cylindrical it also moves the skeleton or organ walls? Muscle
This tissue contains neurons and glial cells Nervous
Characteristics of Epithelial Tissue Apical surface and a basal surface( bound to a basement membrane) Avascular Undergo Cell division frequently
Squamous Flat or squished cells
Cuboidal cube shaped cells
Columnar column shaped cells
Transitional can change shape
What are the two type of Glands Endocrine Exocrine
This gland secretes their products (hormones) DIRECTLY into blood Endocrine
Secretes through a duct to the epithelial surface. Examples are sweat glands, mammary glands, and salivary glands. Exocrine
Package their secretions into secretory vesicles and release secretions by EXOCYTOSIS. Examples include salivary glands, some sweat glands. Merocrine glands
Produce their secretions by the apical membrane around a portion of the glandular cell cytoplasm PINCHES off. Examples are mammary glands, and ceruminous glands of the ear. Apocrine Gland
Formed cells that accumulate a product and the entire cell DISINTEGRATES. Example the olil producing gland in the skin (sebaceous glands) Holocrine Gland
What connective tissue is highly vascular? Bone
What connective tissue is poorly vascular? Dense regular connective tissue.
What connective tissue is avascular? Cartilage
What are the resident cells (stationary) Fibroblasts Adipocytes Mesenchymal Cells Fixed macrophages
What resident cells produce fibers and ground substance Fibroblasts
What resident cells store fat adipocytes
what resident cell is a stem cell that divides to repair tissue damage mesenchymal
what resident cell phagocytize damaged cells or pathogens fixed macrophages
What are the wandering cells (move) Mast cells Plasma Cells Free macrophages
What wandering cell secret heparin to inhibit blood clotting and histamine to dilate blood vessels Mast Cells
What wandering cells produce antibodies plasma cells
what wandering cell phagocytize damaged cells or pathogens free macrophages
what are the protein fibers collagen fibers reticular fibers elastic fibers
what protein fiber is strong, flexible, resist stretching (tendons and ligaments) Collagen fibers
what protein fiber is thin, has branching framework that is tough and flexible (lymph nodes, liver, spleen) Reticular fibers
what protein fiber can stretch and recoil easily (skin, arteries, lungs) elastic fibers
Non cellular material that may be viscous (blood), semisolid (cartilage), or solid (bone) Ground substance
What are the body membranes Mucous membrane (mucosa) Serous membrane Cutaneous membrane (skin) Synovial membrane
This membrane lines area that open to the external environment (digestive, respiratory, urinary, reproductive tracts) and its functions include absorption, protection, and secretion Mucous membrane (mucosa)
This membrane lines body cavities that typically do not open to the external environment (pleura, pericardium, peritoneum) its also produces serous fluid for lubrication Serous membrane
This membrane cover the external surface of the body. Its functions include protecting internal organs and preventing water loss Cuataneous membrane (skin)
This membrane lines some joints in the body. It also secretes synovial fluid to reduce friction among moving bodies Synovial membrane
What does the integumentary system include Skin Nails Hair Sweat Glands and Sebaceous glands
What are the two layers of the skin Epidermis and Dermis
What layer is the superficial layer of the skin Epidermis
What cells divide to generate new cells and replace dead _________ shed at the surface Keratinocytes
Where can you find thick skin Palms of hands and soles of feet
Where can you find thin skin Most of the body except palms and soles.
This is composed primarily of dense irregular connective tissue with collagen fibers. Dermis
What are the two layer of the Dermis Papillary layer (closest to the epidermis) Reticular layer.
What are the functions of the Integument Protect Prevention of water loss and water gain Metabolic regulation Secretion and absorption Immune function Temperature regulation Sensory reception
Hair is found everywhere on the body except for these places Palms of the hands, palmar surface of the fingers, soles of the feet and toes, the lips, and parts of the external genitalia
What are the three phases of hair growth Anagen Catagen Telogen
Where can merorine (eccrine) be found Widely distributed
Where can Apocrine glands be found around the nipples, axillae , pubic and anal regions.
Where is the secretion for merocirne glands Surface of the skin
Where is the secretion for apocirne glands hair folicles
What is the method of secretion for merocrine glands secrete sweat by exocytosis
what is the method of secretion for apocrine gland secrete viscous product containing proteins and lipids by exocytosis it is thick and has proteins and lipids in them
