Question

The triceps brachii flexes the lower arm and is an antagonist to the biceps brachii. In endochrondral bone formation, the long bones of embryos are first made of hyaline cartilage which is then replaced by bone. The insertion of a muscle moved during contraction, the origin does not. Throughout life bone is continually destroyed and replaced. Stress on bone, such as weight-bearing exercise, stimulates bone to be laid down and can help to slow osteoporosis as we age. Cartilage but not bone is an example of a specific type of connective tissue. Some skeletal muscles work synergistically.

Explanation / Answer

Answer:

8. The triceps brachii flexes the lower arm and an antagonist of biceps brachii - False

the bipceps brachii flexes the lower arm and triceps brachii extends the forearm

9. In endocrondal bone formation, the long bone of embryos are made of hyaline cartilage which is then replaced by bone-   True

In endochondral ossification, bone develops by replacing hyaline cartilage. Cartilage does not become bone. Instead, cartilage serves as a template.

10. The insertion of a muscle moves during contraction but the origin does not-   True

11. Throughout life Bone is continuously destroyed and replaced. Stress on bone such as weight bearing exercises, stimulates bone to be laid downand can help to slow osteoporesis as we age- True

12. cartilage but not bone is a siecialized type of connective tissue- False

both cartilage and bone are specialized connective tissues

13. Some skeletal muscle workd synergistically- True

for example, The biceps brachii flex the lower arm. The brachioradialis, in the forearm, and brachialis, located deep to the biceps in the upper arm, are both synergists that help in this motion.
