GENERAL HISTOLOGY

Detailed explanation-1: -Ball-and-socket joints possess a rounded, ball-like end of one bone fitting into a cuplike socket of another bone. This organization allows the greatest range of motion, as all movement types are possible in all directions. Examples of ball-and-socket joints are the shoulder and hip joints (Figure 19.32).

Detailed explanation-2: -The bones in a synovial joint are connected by ligaments. Ligaments are a type of connective tissue and are tough, fibrous and slightly elastic. They connect bone to bone and help keep the joint together.

Detailed explanation-3: -ball-and-socket joint, also called spheroidal joint, in vertebrate anatomy, a joint in which the rounded surface of a bone moves within a depression on another bone, allowing greater freedom of movement than any other kind of joint.

Detailed explanation-4: -Ball-and-socket joints, such as the shoulder and hip joints, allow backward, forward, sideways, and rotating movements.
