Sutural or Wormian bones.
Tendons.
The small flat odd-shaped bones found between some of the large flat bones of the skull are called sutural (Wormian) bones. These bones vary in number and size among individuals and are formed from additional ossification centers. They are considered accessory bones of the skull.
It's called 'bone marrow', and it's function is the manufacturing of haemoglobin. A patient with leukaemia, (cancer of the blood), would geta bone marrow transplant.
The joints found in the skull are mainly fibrous joints called sutures, which connect the cranial bones. These sutures help protect the brain while allowing some flexibility and growth in early life.
The skull is made up of 22 bones, 14 facial bones and 8 cranial bones (excluding a variable number of sutural bones). These bones are classified as flat bones (especially the bones of the cranium) and irregular bones (mainly the bones of the face).
The strong, flexible, and supportive substance found between bones is called cartilage. Cartilage serves as a cushion between bones, allowing for smooth joint movement and absorbing shock. It is found in various parts of the body where flexibility and strength are needed, such as the knees, elbows, and spine.
Sutural bones, which are small, flat, odd-shaped bones found between the bones of the skull are also referred to as Wormian bones. Amount of Wormian bones on the skull differ from person to person.
The outward conical projections on some fetal cranial bones are known as cranial spines. These structures can be found on the occipital bone and are thought to be related to the birthing process, where they may help facilitate passage through the birth canal.
The hip bones.
Synovial fluid is contained in the synovial membrane.
A fibrous joint, also known as a synarthrosis, is a type of joint found between immovable bones. These joints are held together by fibrous connective tissue, allowing for minimal to no movement between the bones. Examples of fibrous joints include sutures in the skull and syndesmoses in the lower leg.
Suture bones are found in the skull. They are called skull bones and are connected by sutures.
