Skeleton System

The connective tissue that connects a muscle to a bone is Tendon.

• Tendons are strong, fibrous connective tissues that transmit the force generated by muscle contraction to the bones, facilitating movement.

Connective Tissues are one of the four main types of tissues in animals. Their main role is to support, connect, and protect other tissues and organs in the body.

Types of Connective Tissues:

1. Loose Connective Tissue (Areolar): Cushions organs and holds them in place.

2. Dense Connective Tissue: Strong tissue found in tendons and ligaments.

3. Cartilage: Flexible support tissue found in joints, ear, nose.

4. Bone: Hard tissue providing structural support.

5. Blood: Fluid connective tissue that transports nutrients and gases.

6. Adipose Tissue: Stores fat and provides insulation.

A fibrous connective tissue that attaches bone to bone is called Ligament.

• Ligaments are tough, elastic bands of connective tissue that stabilize joints by connecting bones to other bones, limiting excessive movement.

• The trachea (windpipe) is reinforced by C-shaped rings of hyaline cartilage, which provide structural support and prevent it from collapsing during breathing, ensuring a clear airway.

Each tooth has 4 main parts, including:

1. Enamel—The outer layer of the tooth and the hardest material in the body.
2. Dentin—The inner layer, the main part of the tooth, and the largest dental tissue.
3. Pulp—Soft tissue inside the tooth that contains the nerve, blood supply, and the ability to produce dentin.
4. Root—The part of the tooth that secures it into the jaw.

Enamel is the outermost layer of the tooth crown, primarily composed of hydroxyapatite, making it the most mineralized and hardest biological substance in the human body.

• It holds the lower teeth in place, assists in mastication and forms the lower jawline.
• The mandible is composed of the body and the rami and is inferior to the maxilla.

• The body is a horizontally curved portion that creates the lower jawline.

The muscle that connects the temporal bone to the jaw is the Masseter.

• The masseter is one of the muscles of mastication (chewing) and is responsible for elevating the mandible, closing the jaw.

• This tissue consists of a single layer of flattened, thin cells, providing a very short diffusion distance for efficient exchange of gases and nutrients.
