Answer 1

Answer:

1. Your back is composed of twenty-four individual bones called vertebrae that are stacked one on top of the other to make up your backbone or spinal column. The entire column sits on the sacrum, a large triangular bone that connects the spine to the hips. The top seven vertebrae in the neck are called the cervical spine.
2. skeleton is an internal or external framework of bone, cartilage, or other rigid material supporting or containing the body of an animal or plant.
3. The skeletal system has many different functions, including supporting the body and giving it shape, protecting internal organs, providing attachment surfaces for skeletal muscles, allowing body movements, producing blood cells, storing minerals, helping to maintain mineral homeostasis, and producing endocrine hormones
4. Fishes are adapted to their environment through the evolution of a few special organs e.g. gills, swim bladders and fins. Gills help in absorbing the oxygen present in the water and swim bladders allow to maintains the proper buoyancy level and fins help to move the fish in the water.
5. The skull consists of three parts, of different embryological origin—the neurocranium, the sutures, and the facial skeleton (also called the membraneous viscerocranium). The neurocranium (or braincase) forms the protective cranial cavity that surrounds and houses the brain and brainstem.

5.The neurocranium is comprised of eight bones: occipital, two temporal bones, two parietal bones, sphenoid, ethmoid, and the frontal bone

6.Penquin,kiwi ,emu

7.Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure. A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.
