anatomical directions, connective tissue & epithelium Flashcards
superior
towards your head
inferior
towards your feet
ventral
anterior, your front
dorsal
posterior, your back
medial
towards midline
lateral
away from midline
limbs - proximal
towards the body
limbs - distal
away from the body
superficial
towards the surface
deep
towards the middle
saggital plane
goes through middle down belly button, divides you into left and right
coronal plane
splits you into ventral and dorsal, like wearing headband
transverse plane
splits you into superior and inferior
what are the four basic tissue types?
epithelial, connective, muscle (smooth, cardiac, skeletal), nervous
what factors are used to classify epithelia?
shape, layers
different epithelia shapes
squamous - flat
cuboidal - cubes
columnar - columns
epithelial classifications by layer
simple - 1 layer
stratified - >1 layer
pseudostratified - simple, all cells attached to basement membrane but the cell nuclei appear at different levels
special epithelial types
pseudostratified - simple, all cells attached to basement membrane but the cell nuclei appear at different levels
transitional - stratified, distensible (stretchy) cells, the surface layer appear domed, used in bladder
