becomes obliterated as the cartilage is
replaced by bone and the joint becomes
synostosis.

The vertebral bodies are united by
fibrocartilage (intervertebral discs)

A

Symphysis

41
Q

Hyaline cartilage + synovial membrane
presents
a joint cavity filled with synovial fluid, a
joint capsule or articular capsule and
articular cartilage.

A

Diarthrosis or Synovial Joint

42
Q

– transmits motor
efferent impulses to
skeletal myocytes.

A

Myoneural junction or motor endplate

43
Q

– receptor located in
between skeletal
myocytes for tension in
the muscle organ.

A

Neuromuscular spindle apparatus or muscle spindle

44
Q
  • located in the tendon close to its
    junction with a muscle organ.
