15229224322	4 types of tissue	epithelial, connective, muscle, nervous	0
15229259285	connective tissue	A body tissue that provides support for the body and connects all of its parts -cells suspend in matrix -cartilage -elastic -hyaline	1
15229299348	tendons	attach muscles to bone	2
15229314273	aponeurosis	muscles to muscle	3
15229319666	ligaments	attach bone to bone -found only in joints -hold bones together	4
15229349794	cartilage	A connective tissue that is more flexible than bone and that protects the ends of bones and keeps them from rubbing together. -fibrocartilage (vertabra discs)	5
15229517542	fibrocartliage ring	pulpy nucleus maade of chondrocytes, collagen fibrils, and proteoglycan aggrecans.	6
15229533596	elastic cartilage	ear, nose epiglottis -change shape and comeback to original shape	7
15229557954	hyaline cartilage	joints, ribcage, trachea, bronchi, larynx, growth plates, growth plates	8
15229609455	Slipped Capital Femoral Epiphysis	occurs when the head of the femur becomes displaced due to a separation at the growth plate	9
15229618963	adipose (fat)	used for heat (insulation)	10
15229623234	sclera	white of the eye	11
15229657168	muscle tissue	A body tissue that contracts or shortens, making body parts move.	12
15229663556	smooth muscle tissue	Involuntary muscle is found in digestive tract, blood vessels, respiratory tract, reproductive system -95% of this in uterus	13
15229681883	digestive tract	moves food through	14
15229704207	striated muscle tissue	skeletal and cardiac -voluntary	15
15229715563	cardiac muscle	Involuntary muscle tissue found only in the heart. contains intercalated discs and desmosomes	16
15229729882	intercalated discs	nervous tissue for two-way conduction for the electrical impulse-connexons which are tubular proteins -skeletal muscle doesn't have this	17
15229785409	desmosomes	epithelial tissue as tight junctions to anchor the muscle fibers together.	18
15229814422	nervous tissue	dentrites and axons.	19
15230140298	exocytosis	dumps content	20
15230144653	myelin sheath	-insulates axon -allows nerve transition -without, will slow down reaction -damage to this will cause multiple scorosis	21
15230169231	epithelial tissue	an avascular tissue with little or no nerve supply, composed of a sheet of cells in which the cells are in direct contact with one another (NO INTERVENING MATRIX) with some or all of the cells standing on a basement membrane. -either simple or stratified	22
15230215132	simple epitelia	the layer of cells is one cell thick. All the cells stand on the basement membrane	23
15230225485	stratified epithelia	the layer of cells is more than one cell thick. Only the inner of innermost layer stands on the basement membrane	24
15230265004	basal layer	the inner or innermost layer of the cells in stratified epithelia	25
15230293264	skin	epidermis and dermis	26
15230309596	stratum corneum	outermost layer of epidermis	27
15230313559	stratum basalis	deepest layer of epidermis	28
15230433694	excretory system	transitional epithelium (urinary bladder)	29
15230445303	transitional epithlium	lines the urinary bladder and parts of the uterus and urethra -stretchy	30
15273294448	endothelium	lining of blood vessels	31
15273301647	simple tubular gland	intestinal glands	32
15273310798	simple branched acinar gland	sebaceous glands (oil producer in skin)	33
15273406055	types of glandular secretion	merocrine, apocrine, holocrine -how a gland secretes its contents	34
15273408143	merocrine	a cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory vesciles	35
15273416444	apocrine	cells which are classified as apocrine BUD their secretions off through the plasma membrane prodicing membrane bound vesicles in the lumen	36
15273424868	holocrine	are produced within the cell followed by the rupture of the plasma membrane thus releasing the contents into the lumen	37
15273437328	integument	skin -protects against invasion of bacteria and other stuff -protects against dehydration -helps with waste removal	38
15273440119	keratinase	only thing that can breach the skin	39
15273447633	epidermis	most outer layer of the layers of skin	40
15273475383	cyanosis	blue skin due to lack of oxygen -happens when very cold (most of the times in lips)	41
15273482837	capilaries	involved in thermal regulatin	42
15273484071	red skin	due to dilation and increased blood flow to the capalaries	43
15273490035	touch receptors	allows touch sense	44
15273492118	arrector pilli muscle	makes hair stand up -controls position in hair	45
15273511210	dermis	true layer; contains blood vessels, nerves, hair follicles	46
15273513379	hypodermis	the layer of skin beneath the dermis, which serves as a storage repository for fat	47
15273520136	hair root plexus	can tell if each hair is moved -allows sense in hair	48
15273527130	lamellated	sense pressure and fast vibration	49
15319744738	epicranius muscle	Broad muscle that covers the top of the skull	50
15319808931	blood, organ capsules	connective tissue	51
