Tutorial 2 Flashcards
what are the 4 main tissue types within the body
- epithelial
- connective
- neural
- muscular
what are the functions epithelial tissue
5
- protection
- secretion
- absorbtion
- thermal regulation
- sensory
what are the functions of connective tissue
supporting organs and cells, transporting nutrients and wastes, defending against pathogens, storing fat, and repairing damaged tissues.
what can connective tissue be categorized as + its subcategory
Connective tissue proper (loose)
* (areolar, adipose, reticular)
Connective tissue proper (dense)
* (elastic, dens regular, dense irregular)
supporting connective
* cartilage (hyaline, elatic, fibro cartilage
* bone
Special/fluid connective tissue
* Blood
* lymph
what are the types of epithelia histology
- simple/stratified
- squamous
- columnar
- keritinized
- ciliated
simple squamous
stratified squamous (non-keratinized)
stratified squamous (keratinized)
simple columnar
simple cuboidal
pesudostratified (ciliated)
stratified cuboidal
what tissue is this? locate:
- collagen fiber
- elatic fiber
- nucleus of fibroblast
Loose connective tissue
- areolar tissue
what tissue is this? locate:
- adipocyte
- neucleus of adipocyte
loose connective tissue
- adipose tissue
what tissue is this? locate:
* the fiber
* capsule of lymph node
loose connective tissue
- reticular tissue (lymph node)
what tissue is this? locate
* collagen fibers
* nucleus of fibroblast
dense connective tissue
- dense regular
what tissue is this? locate
* collagen fibers
* nucleus of fibroblast
dense connective tissue
- dense irregular
how to tell hyaline and elastic cartilage in histology
elastic cartilage will have elastic fibers in its matrix (also only in the ears and epiglottis)
what are the 2 + 1 cutaneous membrane layers.
what are the layers of the epidermal strata (and its neumonic )
come (let’s) grab some beer
- stratum corneum
- stratum lucidum (only in thick skin)
- stratum granulosum
- stratum spinosum
- stratum basal
What are the special cells in in the epidermis (3)
- melanocytes
- langerhans cells
- merkel cells
what are the 2 dermis layers
- papillary region
- reticular region
what are the accessory structures (5)
- hair follicle
- arrector pilae
- sebaceous glands
- sweat gland
- meissner corpuscles
how are skin classified as thick vs thin
based on composition and thickness of epidermis and dermis
- thick skin is hairless
