Intro Flashcards
what is anatomical position
standard position with the body standing, feet forward, feet flat on the floor, head upright, eyes straight ahead, arms by the side with the hands down, palms forward, thumbs unclenched
superior/inferior, example of each
superior - above
inferior - below
shoulder girdle is superior to the hip girdle
medial/lateral, example of each
medial - towards centre of body
lateral - away from body
arm is lateral to chest
chest is medial to arm
anterior/posterior example of each
anterior-in front of
posterior- behind
sternum is anterior to the heart
heart is posterior to the sternum
proximal/distal example of each
proximal- closer to middle
distal - further away
wrist is distal to the elbow
superficial/deep
superficial - closer to skin
deep- closer to heart
muscles are deep to skin, superficial to bones
horizontal/transverse plane
any section perpendicular to the vertical plane
coronal/frontal plane
divides the body into anterior and posterior sections
sagittal
divides the body into left and right portions, the midsagittal planes divides the body into equal left and right halves
epithelial tissues
can be one layer of cells thick - simple epithelium or multiple layers of cells thick - stratified epithelium
shapes of epithelial tissues
flat - SQUAMOUS
cubic - CUBOIDAL
tall - COLUMAR
difference between ligaments and tendons
ligaments - bone to bone
tendons- muscle to bone
describe osseous tissue (bone)
composed of 2 layers outer layer, inner layer
cavity - marrow or medullary cavity containing hematopoietic or blood forming tissue
inner layer of bone tissue vs outer layer
outer layer is made up of compact bone
inner layer is made up of spongy (cancellous bone)
describe skeletal muscle
under direct control of the brain via the motor fibres of the somatic nervous system
composed of very long fibres that have direct innervation by a branch of a motor nerve
