Complete question:Find the structure in the attached file below.
Answer:
The arrows in B and C point to structures that can both be described as LIGAMENTS.
Explanation:
The endoskeleton consist of numerous units of bones jointed at appropriate points. The place where two or more bones are jointed is called a JOINT. There are different types of joints and they include:
-immovable or fixed joints: these joints have saw- like edges which interlock to form sutures at the joints. They are found among the bones of the skull.
- gliding joints: they permit a slight or gliding movement and the bones are held together by discs of fibro- cartilage materials. An example is the joints of the tooth.fibrous connection between a tooth and its socket is a PERIODONTAL LIGAMENT.
- Ball And Socket Joints: this is seen in the shoulder and distal bones.
The following are found in a typical joint section:
- cartilage
- bone ends
- ligaments ( these are strong Fibrous connective tissues that holds two bone ends firmly together in a joint).
