Anatomical Terminology, Techniques, and Tissues Flashcards
Ramus
Branch
Dermatome
Slice of skin innervated by specific sensory nerve of spinal nerve root
Sagittal plane
Cuts body into right and left
Lateral vs medial
Coronal plane
Cuts body into front and back
Anterior/ ventral/ front
Vs
Posterior/ dorsal/ back
H&E stain (hemotoxylin and eosin)
And what’s its disadvantage
Eosin (acidic) stains basic components pink- cytoplasm
Hemotoxylin (basic) stains acidic components bluish- nucleus
Disadvantage: hard to differentiate between connective (and its elements) and muscle
Trichrome stain
Bluish stain specific for connective tissue collagen (type 1 collagen)
Can be used to distinguish connective and muscle
What color will elastic and collagen appear using an elastic fiber stain?
Elastic- dark purple
Collagen- tannish red
Myotome
Specific area of skeletal muscle receiving specific innervation
Costa
Rib
Where does epithelium blood supply come from
Epithelium is AVASCULAR
Nutrients via diffusion from adjacent blood vessels in underlying connective tissue
Compare cellular elements of loose vs dense connective
Loose- more cellular components than fibrillin component (mostly collagen)
Dense- more fibrillin components
The underlying loose, areolar (fatty) connective tissue is ___
Superficial fascia
Invests all of the deeper structures, completely surrounds
What type of tissue is deep fascia
Dense irregular connective
Provides stiff investment for bone, muscle, neuro vascular structures between
Most prevalent type of cartilage, and where is it found?
Hyaline cartilage
Articulating surfaces of bones at synovial joints
dysdiadochokinesis
difficulty with rapidly alternating movements (fine motor skill)
