Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space. Hyaline cartilage is found in the nose, ears, trachea, parts of the larynx, and smaller respiratory tubes. Fibrous cartilage has the fewest cells so it has the most intercellular space. Fibrous cartilage is found in the spine and the menisci.
Skeletal and cardiac muscles have striations that are visible under a microscope due to the components within their cells. Only skeletal and smooth muscles are part of the musculoskeletal system and only the muscles can move the body. Cardiac muscles are found in the heart and are used only to circulate blood; like the smooth muscles, these ...
When the GAG chain functions properly, it controls the maturation speed of chondrocytes and ensures enough cells gather in the cartilage anlage. Xylt1 is an essential gene in regards to chondrocytes and proper skeletal formation, and is a key factor in the close regulation of maturation.
Hyaline cartilage is the most common kind of cartilage in the human body. [2] It is primarily composed of type II collagen and proteoglycans. [2] Hyaline cartilage is located in the trachea, nose, epiphyseal plate, sternum, and ribs. [2] Hyaline cartilage is covered externally by a fibrous membrane known as the perichondrium. [2]
Growth and remodeling have a major role in the cause of some common soft tissue diseases, like arterial stenosis and aneurisms [13] [14] and any soft tissue fibrosis. Other instance of tissue remodeling is the thickening of the cardiac muscle in response to the growth of blood pressure detected by the arterial wall.
Muscle cells (myocytes) form the active contractile tissue of the body. Muscle tissue functions to produce force and cause motion, either locomotion or movement within internal organs. Muscle is formed of contractile filaments and is separated into three main types; smooth muscle, skeletal muscle and cardiac muscle.
The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage.)
When the motor nerve is stimulated there is a delay of only 0.5 to 0.8 msec between the arrival of the nerve impulse in the motor nerve terminals and the first response of the endplate [7] The arrival of the motor nerve action potential at the presynaptic neuron terminal opens voltage-dependent calcium channels, and Ca 2+ ions flow from the ...
