The bones of the skull are considered flat bones. The vertebral column supports the head and encloses the spinal cord, which mean that it ranges from the base of the skull down to the pelvis. The vertebral column is composed of 26 individual bones, these bones are referred to as vertebrae. The spinal column is divided into five different areas containing groups of vertebrae: There are seven cervical vertebrae in the neck; twelve thoracic vertebrae in the upper back corresponding to each pair of ribs; five lumbar vertebrae in the lower back; five sacral vertebrae which are fused together to form one bone called the sacrum; four coccygeal vertebrae that are fused together to form the tail-bone. The vertebrae support the head and trunk of the body.
This plate is a layer of hyaline cartilage that allows the diaphysis of the bone to grow in length but not in width. • Articular cartilage is a thin layer of hyaline cartlage covering the epiphysis where the bone forms a joint with another bone. This
4. Compare and Contrast the microscopic appearance, location and function of spongy and compact bones? a. Long bones consist mostly of compact bone tissue in the diaphysis and have some amounts of spongy bone tissue in the epiphyses. Short, flat, and irregular bones consist mainly of spongy bone tissue, except at the surface, where there is compact bone.

Bone tissue structure Bone is hierarchically organized. Zooming in the bone structure (Fig. 4a), we find the osteons or Haversian systems, which are the basic unit of structure of compact bone. Osteons consist of concentrically arranged layers, or lamellae, of compact bone tissue, that surround a central canal, the Haversian canal, where bone’s blood supplies and nerves can be found (Fig. 4b).
The coccyx it attached at the end of the sacrum through a vestigial disc and is also connected to the sacrum with ligaments. There is very limited movement between the coccyx and the sacrum. “The small coccyx consists of three to five (most often four) coccygeal vertebrae that usually begun fusing by the age of 26. The coccyx provides an attachment site for a number of ligaments and for muscle that constricts the anal opening. The first two coccygeal vertebrae have transverse processes and unfused vertebral arches.
Long bones – The major bones of the arms (humerus, radius, and ulna) and the legs (the femur, tibia, and fibula) are all long bones. Short bones – The short bones include all of the metacarpals and phalanges in the hands, the metatarsals and phalanges in the feet, and the clavicle (collarbone). Flat bones – The flat bones include the scapula (shoulder bone), the ribs, and the sternum (breastbone). Seasamoid bones – patella (knee cap) Irregular - vertebrae (spine) and the mandible (jaw) Human skeleton - anterior view Human skeleton - posterior view An example of a sesamoid bone (patella) The vertebral column (spine) Functions of the skeletal system are: 1. Protection - the cranium and ribs protect the brain and vital organs in the chest.
Their are many major bones in the body,im going to list the 15 that i believe are the most important ones with a muscle that attaches to it. The femur, located in the thigh area attached by the quadriceps know as the great extensor muscle of the knee. The humerus, located in the shoulder area attached by the deltoids. The calcaneus, located on our bottom half of the leg is attached by the gastrocnemius starts from the knee to the heel. The next bone shouldnt be in the list but im interested in it and how it combines with other bones to form the cranium, the parietal bone located in the right side of the skull and i think theirs no muscle attached to this bone.
