Answer:
1)The femur is the longest and, by some measures, the strongest bone in the human body.
2)Examples of voluntary muscle are the biceps, triceps and quadriceps. The biceps are the muscle on the inside of the arm above the elbow. Bending the...
3) Ball & Socket Joint. ... The shoulder and hip joints are the only ball-and-socket joints in the human body due to the need for great motion at the end of the body's limbs and the vast amount of musculature needed to move and support such flexible joints.
4)The bone marrow of essentially all the bones produces red blood cells until a person is around five years old. The tibia and femur cease to be important sites of hematopoiesis by about age 25; the vertebrae, sternum, pelvis and ribs, and cranial bones continue to produce red blood cells throughout life.
5)These include fibrocartilaginous and hyaline joints, which usually occur at the midline. Some examples of secondary cartilaginous joints in human anatomy would be the manubriosternal joint (between the manubrium and the sternum), intervertebral discs, and the pubic symphysis.
6). a type of contractile tissue that is marked by transverse striations; it is concerned with moving skeletal parts to which it is usually attachedAlso called: skeletal muscle Compare smooth muscle.
7)Pivot joints allow for rotation around an axis, such as between the first and second cervical vertebrae, which allows for side-to-side rotation of the head. (b) The hinge joint of the elbow works like a door hinge.
8)The shoulder joint is formed by the articulation of the head of the humerus with the glenoid cavity (or fossa) of the scapula. This gives rise to the alternate name for the shoulder joint – the glenohumeral joint. Like most synovial joints, the articulating surfaces are covered with hyaline cartilage.
9)The synovial fluid (SF) of joints normally functions as a biological lubricant, providing low-friction and low-wear properties to articulating cartilage surfaces through the putative contributions of proteoglycan 4 (PRG4), hyaluronic acid (HA), and surface active phospholipids (SAPL).

Answer:
1) The femur is the longest and, by some measures, the strongest bone in the human body.
2)An immovable joint is an articulation between bones in which no movement occurs. It is also referred to as synarthrotic (meaning immovable)
