Answer:
1. setae
Answer. Tiny claw-like bristles called setae. Actually, the earthworms use the setae to anchor them, while waves of muscular contractions alternately shorten and lengthen the body. This movement is called peristalsis and helps the earthworms to move.
2.Synovial joints enable the human body to move.
3.The patella, also known as the knee cap or kneepan, is a thick, circular - triangular bone which articulates with the femur and covers and protects the anterior articular surface of the knee joint
4.Serpentine method: This motion is what most people think of when they think of snakes. Snakes will push off of any bump or other surface, rocks, trees, etc., to get going. They move in a wavy motion. ... This movement is also known as lateral undulation.
5.Vertebrates
Vertebrates are animals with backbones. This group includes reptiles, fish, amphibians, birds, and mammals.
6.Bone marrow is a semi-solid tissue found within the spongy or cancellous portions of bones. In birds and mammals, bone marrow is the primary site of new blood cell production or haematopoiesis. It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.
7.Sacrum - the main function of the sacrum is to connect the spine to the hip bones (iliac). There are five sacral vertebrae, which are fused together. Together with the iliac bones, they form a ring called the pelvic girdle.
8.The joints of the vertebral arches are the zygapophysial joints (often called facet joints). These articulations are plane synovial joints between the superior and the inferior articular processes (zygapophyses) of adjacent vertebrae. Each facet joint is surrounded by a thin, loose joint capsuThe joints of the vertebral arches are the zygapophysial joints (often called facet joints).

9.A tendon is a tough band of connective tissue that connects a muscle to a bone. Tendons are similar to ligaments, except that ligaments join bones to each other.
10.spinal column, spine, and vertebral column.
11.Bones are the hard structure which forms the skeleton
12.Ball and socket joint – the rounded head of one bone sits within the cup of another, such as the hip joint or shoulder joint. Movement in all directions is allowed. Saddle joint – this permits movement back and forth and from side to side, but does not allow rotation, such as the joint at the base of the thumb.
13.pivotal joint
The joint where our neck joins the head is a pivotal joint.
14.A baby's body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby's bones are made entirely of a special material called cartilage (say: KAR-tel-ij). Other bones in a baby are partly made of cartilage.
15.206 bones
The adult human skeleton is made up of 206 bones.
