Question

Identify the following:

a. Immovable joint between flat bones of the skull united by a thin layer of dense connective tissue
b. Temporary joint in which bones are united by bands of hyaline cartilage
c. Slightly movable joint in which bones are united by interosseous membrane
d. Joint formed by union of tooth root in bony socket

Answer 1

The immovable joint between flat bones of the skull united by a thin layer of dense connective tissue is called a suture. The temporary joint in which bones are united by bands of hyaline cartilage is known as a synchondrosis. A slightly movable joint in which bones are united by an interosseous membrane is called a syndesmosis. The joint formed by the union of a tooth root in a bony socket is called a gomphosis.

Step-by-step explanation:

The immovable joint between flat bones of the skull united by a thin layer of dense connective tissue is called a suture. This type of joint strongly unites adjacent skull bones, providing protection for the brain.

The temporary joint in which bones are united by bands of hyaline cartilage is known as a synchondrosis. An example of a temporary synchondrosis is the epiphyseal plate in growing long bones.

A slightly movable joint in which bones are united by an interosseous membrane is called a syndesmosis. This type of joint is found between parallel bones such as the radius and ulna in the forearm.

The joint formed by the union of a tooth root in a bony socket is called a gomphosis. It is a specialized fibrous joint that anchors a tooth to its socket in the jaw.

Answer 2

a. Suture joint is the main immovable joint present between the flat bones of the skull. The suture is a type of the fibrous joint and resist the motion between the body parts.

b. Synchondrosis joint is the joint in which the hyaline cartilage band are united to joint the bones. This is a type of temporary joint.

c. Syndesmosis joint unite the interosseous membrane. This joint provide the slight movement of the bones.

d. Gomposis joint is present in the socket of the tooth. This joint is formed by the union of the roots of the tooth in the bone socket.

Thus, the correct answer are a. Suture joint, b. Synchondrosis, c. Syndesmosis and d. Gomposis joint
