Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
which are the three types of joints?
A
Fibrous or immovable, Cartilaginous or slightly moveable, Synovial or freely movable
B
Fibrous or immovable, Cartilaginous or slightly moveable,
C
Fibrous or immovable
D
Synovial or freely movable
Explanation: 

Detailed explanation-1: -Histologically the three joints in the body are fibrous, cartilaginous, and synovial. Functionally the three types of joints are synarthrosis (immovable), amphiarthrosis (slightly moveable), and diarthrosis (freely moveable).

Detailed explanation-2: -Fibrous Joints The amount of movement allowed depends on the length of the connective tissue fibers uniting the bones. Although a few are slightly movable, most fibrous joints are immovable. The three types of fibrous joints are sutures, syndesmoses, and gomphoses. Sutures are immobile joints in the cranium.

Detailed explanation-3: -Knees, elbows, and shoulders are examples of synovial joints. Since they allow for free movement, synovial joints are classified as diarthroses. Figure 38.10.

Detailed explanation-4: -Slightly movable joints are called amphiarthroses. The singular form is amphiarthrosis. In this type of joint, the bones are connected by hyaline cartilage or fibrocartilage.

Detailed explanation-5: -Synovial joints are the most common type of joint in the body (see image 1). These joints are termed diarthroses, meaning they are freely mobile.
