Skeletal System/Tissues, Joints, and Skeletal Muscle (Skeletal…

- - - - Uniaxial, hole and axle, has only a vertical axis with rotation
    - - Oval bump in articular surface, medial/lateral axis with anterior/posterior axis that gives flexion and extension, and adduction and abduction, respectively
    - - Uniaxial, cylinder in trough, medial/lateral axis with flexion and extension
    - - Spherical ball (head) with the medial/lateral, anterior/posterior, and vertical axis that allows flexion and extension, adduction and abduction, and rotation, respectively
    - - Nonaxial, flat articular surfaces that glides
    - - Concave and convex articular surfaces that has medial/lateral, and anterior/posterior axis with adduction and abduction, and flexion and extension, respectively
  - - - Bones connected by ligaments and movement depends on length of fiber
    - - Peg-in-joint socket like teeth
    - - Bones of the skull tightly held together by some fibrous tissue
  - - - Immobile, hyaline cartilage joins bones ie. costal cartilage of ribs, epiphyseal plate
    - - Fibrocartilage that joins bones, only slightly mobile
- - - - Rigid connective tissue that makes up most of the skeletal system
    - - Fibrous elastic tissue that connects ends of bones to make a joint
    - - Fibrous connective tissue that are flexible but not elastic and that connects muscle to bone
    - - Flexible tissue that often times line the cavities of joints for articulation
  - - - The inside of bone made of trabeculae which contains the yellow and red bone marrow
    - - The dense outer layer of bone
  - - - Creates red blood cells
    - - Stores energy as fat and makes blood cells in emergencies
  - - - Are mature osteoblasts that becomes surrounded by bone matrix
    - - Immature osteocytes that secretes bone matrix
    - - Large cells that eats dead osteocytes and destroys mineral and organic parts of the bone matrix
- - - - Sarcomeres
        
        Basic unit of contraction that makes up each myofibril
        
        Elastic titin filament
        
        Thick myosin filament with myosin heads
        
        Thin actin filament
        
        H zone
        
        Thick filaments
        
        A band
        
        Thick and thin filaments overlap
        
        M line
        
        Thick filaments linked with accessory protiens
        
        I band
        
        Thin filaments
    - - Plasma membrane of each muscle fiber
    - - Powers the myocyte
    - - Myocytes are very long and requires multiple nuclei to control them
  - - - Made of fibers and when in a group makes a fascicle
        
        Endomysium
        
        Thin layer of loose connective tissue made mostly of reticular fiber that contains blood vessels surrounding each myocyte
        
        Epimysium
        
        Made of dense irregular connective tissue that surrounds each muscle
        
        Perimysium
        
        Layer of fibrous connective tissue (dense) surrounds a fascicle
