- - - - Fasicle
        
        A group of fasicles makes a hole muscle
        
        Perimysium: Covers each fasicle and contains blood vessels within, made of dense irregular connective tissue. Also it binds all the fasicles together to create a hole unit.
      - Within each muscle fiber there organelles.
      - Within each muscle fiber there is endomysium, composed mostly of reticular fibers which allows space for small blood vessels to run next to muscles.
      - Myofibrils are what makes up a muscle fiber.
      - Deep fascia: Made of dense irregular connective tissue and bundles groups of muscle together.
      - Transverse tubules (T tubules) When the sacrolemma goes inward to creat a tube inside the cell
      - Sacrolemma: Plasma membrane of a muscle fiber/cell
      - Sacroplasmic reticulum: Smooth ER, stores calcium, net-like structure.
      - Terminal cisterns: storage place for calcium
      - Mitochondria: energy organelle of muscle
- - - - Pivit joint
        
        Which includes the ulna and radius when you move/rotate the radius. This type of joint is also located in the atlas and axis of the cervical vertebra
      - Condylar joint
        
        Located in the metacarpal and phalgeal joints.
      - hinge joint
        
        In the elbow joint and between the tarsals
      - Carpometacarpal joint
        
        Is a joint of the thumb
      - Plain joint
        
        Glyding motion, in the intercarpal joint, which is between the carpals
      - Ball and socket joint
        
        Located in the shoulder, and hip these joint provide flexion and extension.
- - - - When your body/diet dose not provide enough calcium it relies on the bone storage system as back up.
  - - - Hyaline cartilage (trachea rings, larynx, tip of nose, costal cartilage).
        
        Articular cartilage is a type of hyaline cartilage but is located where there is a moving joint.
        
        one are connected by
      - Fibro cartilage (inter vertebral discs, pubic symphesis, and the meniscus.
      - Elastic cartilage (outer ear, and epiglottis)
    - - 35 5 of bone is organic consisting of cells and extra-cellular matrix.
      - 65% of bone is inorganic consisting on minerals such as (calcium, and phosphorus) the minerals provide bone with its hardness, and aids in resisting compression.
  - - - Have a cube shape to them such as the (talus bone, tarsals, and carpals.
    - - Flat bones are thin and most of the time curved such as the cranial bones, scapula, and ribs).
    - - Most of the bones in the limbs are long bones such as the humerus, femur, patella. Also the bones of the fingers and toes are considered long bone like the meta-carpals, and phalanges.
    - - Have a various shape to them and don't fit in the other cone categories such as the (vertebra, and hip bones).
  - - - Has no osteons in flat bones, are made of many trabecula, osteocytes, and extracellular matrix.
        
        Spongy bone is located in the ends of long bone, and inside the other types of bone, also a location for red bone marrow.
    - - The outer part of every bone, composed of many osteons packed together.
  - - - There are two sections of epiphysis on a long bone the two ends of the long bone. At these ends is where the internally spongy bone is located. Also adding some padding on the ends coving the bone is articular cartilage.
    - - This part of a long bone is considered the shaft of the bone and it is in this area where the internally medullary cavity is located containing the endosteum within.
    - - Is a membrane that cover all of the long bone except where then ends are and there is articular cartilage.
  - - - Osteoclasts have multiple nuclei, have micro villi, break down tissue for re-absorption, secrete enzymes, perform phagocytosis to break down organic material, and the inorganic material is released back into the blood stream.
