Injuries to carpals, humerus, radius, ulna, clavicle, metacarpals, metatarsals, tarsals and various flat bones like scapulae would cause issues.

Bones are abnormally weak, brittle, and highly flexible. In severe cases, individuals may have abnormal bone formation as manifested by thicker and longer bones, resulting in a taller stature.
-
Bones are abnormally weak and prone to breakage and fracturing upon mild trauma. In severe cases, individuals may have abnormal bone formation as manifested by thicker and longer bones, resulting in a taller stature.

Bones are abnormally weak and highly flexible. In severe cases, individuals may have abnormal bone formation as manifested by thinner and/or shorter bones, perhaps resulting in a shorter stature.

A therapeutic drug that inhibits osteoblast activity would be useful. Designing a drug that enhances the bone formation activity of osteoclasts may also be a good strategy.

The graph shows the frequency of joint injury per 1000 exposure hours among malerugby players sustained during a season against the site of injury. Shoulder and hip joints are ball and socket. Elbow and knee joints are hinge. Wrist joint is condyloid.
Make a claim based on this graph.
-
Hinge joints are stronger than ball and socket joints.
-
Among ball and socket joints, the one with less movement is stronger.
-
Among hinge joints, the one with more movement is stronger.
-
Condyloid joints are stronger than hinge joints.
-
Both the hip joint and knees are flexed.
-
Both the hip joint and knees are extended.
-
The hip joint is extended and the knees are flexed.
-
The hip joint is flexed and the knees are extended.

Voluntary muscles cannot be consciously controlled, as is the case with cardiac muscles. Involuntary muscles can be controlled by an individual’s will, as is the case with skeletal muscles.

Myosin heads would detach rapidly from the actin-binding sites, resulting in muscle relaxation. In a live person this causes rigor mortis, while in a recently dead person it results in “writer’s cramp.”

Myosin heads would not detach from the actin-binding sites, resulting in muscle stiffness. In a live person this causes rigor mortis, while in a recently dead person it results in “writer’s cramp.”
