Skeleton
Appendicular skeleton upper limb :
Pectoral girdle
Appendicular Skelton lower limb:
pelvic girdle
Pelvis is supportive and protective and doesn’t move as much as pectoral girdle
Joints:
fibrous joints are stiffer
If we want movement, we need synovial joint
Sterner povicular (like the joint between clavicle sad menuvium) we don’t want it to move
hinge joints allow Flexion and extension (like in fingers)
Pivot joint allows u to say no
Saddle joints allow u to move side to side
Ball and socket joint is like in shoulder
Muscles:
skeletal muscle needs to be present thats pullimg and contracting at joints
Moves bones too
Muscles can attach directly to bone or indirectly via tendons, fascia or organ
Superficial Fascia is loose connective tissue that’s embedded into subcutaneous layer
Superficial fascia allows skin to move easily and is a safety layer for skin. MAINTAINS SHAPE.
Deep fascia gives support. Innervated so can sense pain and movement and pressure, temp etc.
Muscle compartment- groups of muscles surrounded by deep fascia that have similar functions and also share same neurovascukar supply.
Sometimes deep fascia becomes thickened
Dorsiflexion is flexing foot up. Plantarflexion is standing on toes
Inversion is big toe up litttle toe on ground. Eversion is big toe down little toe up.
