[RAP0 21LAB] PRELIM: Lesson 4 Connective Tissue

Connective Tissue

Is one of the four main types of tissue in the body, providing support, protection, and structure.

Loose and Dense Connective Tissue

2 Proper Connective Tissue

Areolar; Adipose; Reticular Tissue

3 Loose Connective Tissue

Areolar Tissue

• Loose Connective Tissue

• Supports and cushions organs, found beneath the skin.

Adipose Tissue

• Loose Connective Tissue

• Stores fat, provides insulation, and cushions organs.

Reticular Tissue

• Loose Connective Tissue

• Forms the framework of organs like the spleen and lymph nodes.

Dense Regular; Dense Irregular; Elastic

3 Dense Connective Tissue

Dense Regular

• Dense Connective Tissue

• Found in tendons and ligaments; provides strong, unidirectional support.

Dense Irregular

• Dense Connective Tissue

• Found in dermis and joint capsules; provides strength in multiple directions.

Elastic

• Dense Connective Tissue

• Found in large arteries and some ligaments; allows stretching and recoil.

Cartilage and Bone

2 Supportive Connective Tissue

Cartilage

• Supportive Connective Tissue

  • Hyaline Cartilage

  • Elastic Cartilage

  • Fibrocartilage

Hyaline Cartilage; Elastic Cartilage; Fibrocartilage

3 Cartilage (Supportive Connective Tissue)

Hyaline Cartilage

• Cartilage (Supportive Connective Tissue)

• Found in the nose, trachea, and joints; provides smooth movement.

Elastic Cartilage

• Cartilage (Supportive Connective Tissue)

• Found in the ear and epiglottis; provides flexibility.

Fibrocartilage

• Cartilage (Supportive Connective Tissue)

• Found in intervertebral discs and knee joints; provides shock absorption.

Bone

• Osseous Tissue

• Supportive Connective Tissue

  • Compact ___

  • Spongy ___

Compact and Spongy Bone

2 Osseous Tissue (Supportive Connective Tissue)

Compact Bone

• Bone (Osseous Tissue) (Supportive Connective Tissue)

• Dense, forms the outer layer of bones, provides strength

Spongy Bone

• Bone (Osseous Tissue) (Supportive Connective Tissue)

• Found in the inner part of bones, lightweight, and contains bone marrow.

Blood and Lymph

Fluid Connective Tissue

Blood and Lymph

2 Fluid Connective Tissue

Blood

• Blood and Lymph (Fluid Connective Tissue)

• Contains red blood cells, white blood cells, and platelets; transports nutrients and oxygen.

Lymph

• Blood and Lymph (Fluid Connective Tissue)

• Contains white blood cells and helps in immune defense and fluid balance.
