Skeletal system/tissues:star:, joints:star: and skeletal muscle:star:
-
-
-
Uniaxial movement[flexion and extension]-medial/lateral axis:cylinder trough ex)Elbow joints, interphalangeal joints.
-
called Peg-in socket fibrous joint or "Bolt"-between teeth alveoli periodontal ligament, which is held tooth in socket -little movement
-
Generate tension or force when pulling on attachement point.;Actin and myosin proteins produce contractile force in every cell in the body.
Immobile joint between Ist rib's costal cartilage and the manubrium of the sternum;Hyaline cartilage united(ex:Epiphyseal plate)
Longer than suture; Bundle of dense regular connective tissue- distal tibiofibular joint which composed of in the interosseous membrane (ex:carpals and tarsals), little movement
It consist of pubic symphysis and intervertebral joint which act as shock resilient absorber- slightly movement/ made of Hyaline cartilage(outside) and fibrocartilage(inside).
Occur in the temporomandibular(jaw) joint, sternoclavicular joint, knee joint and few others
-
-
-
-
Gliding/nonaxial movement EX:intercarpal joints, intertarsal joints,joints between vertebral articular surfaces
-
Stimuli and nerve signal(electrical signal) impulse contraction in muscle cells
-Stimuli excite muscle cells/ cause nerve impulse through plasma membrane.
-produce nerve signal(electrical signal) by stimulus
-
Consist of fibrous layer(D.I.C.T) which covered by periosteum layer of joining bones and synovial membrane(loose C.T) which is not contain by cartilage and functions is to make synovial fluid.
-
called "ovum eggs"-Liquid inside the joint cavity also occurs within the articular cartilage which squeezes out of articular cartilage
called "End sacks"-perpendicular channels and junction between A-band in a myofibril and its adjacent I-bands (A-I junctions)
-
-
Surrounding layer of each fascicle -Dense irregular connective tissue(Fibrous); It contains blood vessels inside a fascicle
An outer layer of Dense irregular connective tissue; Sometimes it binds or blend with deep fascia that neighboring muscles.
-
-
Bursa:ligaments,muscle,skin tendons or bones overlie each other and rub together.Tendon sheath:narrow canals as in the carpel tunnel of the wrist.
Uniaxial movement;rotation;ex)proximal radioulnar joints, atlantoaxial joint
Biaxial movement-flextion/extension/addction/abduction-ex)Metacarpophalangeal joints,wrist joints
Consist of Hyalinecartilage,Elasticcartilage,Fibrocartilage-FIexible support for certain structures in adult humans including the noses, knees, ankles, and ears.
