A1. Osteology and Neuromuscular Systems in General Flashcards
Median (sagittal) Plane
Down the middle so that you have a left side and a right side.
Parasagittal
Something slightly off-center
Coronal Plane
Front and back
Tranverse (axial) plane
Top and bottom
Anterior-posterior
front-back
ventral-dorsal
belly-back
superior-inferior
high-low
proximal-distal
closer to the midline-farther from the midline
superficial-deep
outer-underneath
Ipsilateral-contralateral
same side-opposite side
epiphyseal plate
growth plate in bones
nutrient foramens
where the blood vessel goes into the bone
periosteum
completely covers surface of the bone. has a nerve supply with a lot of pain receptors.
Note: when you fracture a bone the periosteum is what causes the pain - not the bone itself.
joint
where bones join
fibrous joint
joint that provides minimal movement.
Ex: skull plates are joined together by a fibrous joint called a suture.
Ex: interosseous membrane between radius and ulna.
Synovial joint (4 parts)
- hyaline cartilage
- synovial membrane
- synovial fluid
- fibrous capsule
Fusiform
something that looks like a bicep muscle with a big belly and a tendon
quadrate
flattened and square-ish
Ex: pects
circular
circular muscle that makes a sphincter
Ex: eye
pennate
muscle shaped like a feather (unipennate, bipennate, multipennate).
Ex: Deltoid
Abduction
away
Adduction
towards
medial rotation
internal
lateral rotation
external
