Orientation and Tissues
Question | Answer |
---|---|
Anatomy | study of structure of body and how the parts relate to each other |
Physiology | study of function of body and its divided by system |
9 anatomical divisions of abdominal cavity from left down | Right hypochondriac, right lumbar, right iliac, epigastric, umbilical, hypogastric, left hypochondriac, left lumbar, left iliac |
What are the functions of epithelial tissue? | Protection, absorption, secretion, and filtration |
Know at least 1 location of each of the 8 types of epithelial tissue. | Simple squamous-lungs simple cuboidal-kidneys simple columnar-kidney peseudostratified-trachea stratified squamous-skin stratified cuboidal-sweat stratified columnar-conjunctiva transitional-ureters |
What are the special characteristics of epithelial tissue? | specialized contacts, polarity, basement membrane, regeneration, avascularity, cellularity |
What are the three types of epithelial membrane? | mucous membrane, cutaneous membrane, and serous membrane |
What is the difference between endocrine gland and exocrine gland? | Endocrine-ductless gland; glands secrete hormones into the extracellular space where they make their way into the bloodstream exocrine-secrete product into ducts which open onto body surfaces or into body cavities |
functional classification of glands | merocrine-secrete products by exocytosis holocrine-product accumulates until cell ruptures and releases product apocrine-product accumulates at apex of cell apex pinches off and product is releases cell repairs itself and process starts over |
what are the 4 types of connective tissue? | connective tissue proper, cartilage, bone, and blood |
what are the 5 functions of connective tissue? | binding, support, protection, insulation, transportation of blood |
what are the 3 elements of connective tissue? | ground substance, fibers, and cells |
what are the 3 types of fibers found in connective tissue? | collagen; made of collagen protein, it is tough and provides high tensile strength elastic; made up of elastin protein, it stretches and recoils; it snaps connective tissue back to normal length Reticular; made up of fine collagenous fibers |
10 types of cells found in connective tissue? | fibroblast, fibrocyte, chondroblast, chondrocyte, osteoblast, osteocyte, hemocytoblast, hemocytocyte, macrophages, and mast cells |
what are the 3 types of loose connective tissue? | areolar adipose reticular |
what are the 3 types of dense connective tissue? | dense regular dense irregular elastic |
what are the 3 types of cartilage? Name at least 1 location of each | hyaline-ends of bone fibrocartilage-discs of knee elastic cartilage- ear |
what is the difference between the inflammatory response and the immune response? | inflammatory-nonspecific; happens when tissues are injured immune-specific; cells mount attack against invaders |
steps in tissue repair | 1) capillaries dilate and become very permeable 2) forms clot 3) Organization- clot is replaced by granulation tissue 4) regeneration of surface epithelium- inbetween scab and granulation tissue |
what is a zygote? | fertilized egg |
what is a blastula? | hollow ball of cells |
what is the blastopore? | blastula invaginate at a point known as: |
what is the gastrula? | invagination causes a new layer of tissue to be formed within blastula |
what are the 3 primary germ layers called? | ectoderm, mesoderm, endoderm |
which primary germ layers give rise to connective tissue? To epithelial tissue? | connective tissue-mesoderm epithelial tissue- all 3 layers |
