Anatomy Flashcards
Anatomical Position
Face up, hands out to the side, palms facing upward, with thumbs pointing away from body
Anatomical Planes
Midsagittal: Median, Right on middle of body from head to toes
Parasagittal: Paramedian, Lateral to or beside the sagittal plane and parallel to it.
Coronal: Frontal, From ear to ear, divides back and front.
Horizontal: Transverse, Cuts through body horizontally, cuts top half of body from bottom half.
Lateral vs Medial
Lateral = away from midline Medial = Towards midline
Anterior vs Posterior
Anterior = In front of the coronal plane Posterior = Behind the coronal plane. Ex. Nose is anterior to the ears.
Superior vs Inferior
Superior = Above the horizontal plane Inferior = Below the horizontal plane. Ex. Head is superior to the neck.
Looking at MRI what plane do we see?
We see the axial (horizontal plane) as in we’re standing at the foot of the bed looking up to their feet.
Transverse Cut
Differs from horizontal in upper arms.. Since need to cut at right angles can’t cut along horizontal plane in arms in anatomical position!
Anatomical Regions
Head and neck, thorax, abdomen, pelvis, upper limb, lower limb
Cavities
Cranial cavity, thoracic cavity, vertebral cavity, abdominal cavity, pelvic cavity
Proximal vs Distal
Proximal = Closer to body Distal = Farther from body
Layers of the Skin
Epidermis: stratified squamous epithelium, build for abrasion!
Dermis: Dense irregular connective tissue layer, contains nerves and blood vessels.
Superficial Fascia (subcutaneous tissue): Loose connective tissue with fat! and platysma muscle
Deep Fascia: Important in lower limb for venous return
Skeletal Muscle
Superficial vs Deep
Superficial = closer to skin or body surface
Deep: Away from skin or body surface, towards core of body
Burns
1st Degree: Involves epidermis
2nd: Involves the dermis as well
3rd: goes down to deep fascia
