Study Notes
Classification of Tissue
-
Bone (Osseous Tissue)
- Highly vascular, composed of osteocytes located in lacunae.
- Characterized by a hard, calcified matrix containing collagen fibers.
-
Blood (Connective Tissue)
- Contains blood vessels with a matrix known as plasma.
-
Nervous Tissue (Neurons)
- Found in the brain, spinal cord, and nerves.
- Supported by neuroglia, which protect, nourish, and insulate neurons.
-
Skeletal Muscle
- Attaches to bones and skin; long, striated, multinucleated cells.
- Under voluntary control, enabling conscious movements.
-
Cardiac Muscle
- Exclusive to the heart; striated and typically uninucleated.
- Functions involuntarily, responsible for heart contractions.
-
Smooth Muscle
- Present in the walls of hollow organs; not striated and uninuclear.
- Operates involuntarily, managing internal bodily functions.
-
Cartilage Elastic (Connective Tissue)
- Provides support to structures like the external ear.
- Composed of a rubbery solid matrix, allowing flexibility.
-
Fibrocartilage (Connective Tissue)
- Found in intervertebral disks and knee joints.
- Offers strength to resist compressive forces.
-
Hyaline Cartilage (Connective Tissue)
- Contains chondrocytes; present in structures like the ribs and nose.
- Smooth texture, important in articular surfaces of joints.
-
Dense Irregular Connective Tissue
- Forms fibrous capsules surrounding organs and joints.
-
Dense Regular (Dense Connective Tissue)
- Found in tendons and ligaments, connecting muscle to bone.
- The primary cell type is fibroblast, responsible for matrix production.
-
Reticular (Loose Connective Tissue)
- Primarily located in the spleen, providing structural support.
-
Adipose (Loose Connective Tissue)
- Located within the abdomen and breasts; serves as a reserve for food and insulation.
- Contains a gel-like matrix facilitating fat storage.
-
Areolar (Loose Connective Tissue)
- Provides cushioning for organs, surrounding capillaries.
- Characterized by a gel-like matrix with fibroblasts as main cells.
-
Transitional Epithelium
- Specialized tissue designed to stretch, found in the urinary bladder.
-
Stratified Squamous Epithelium
- Lines the esophagus, offering protection against abrasion.
-
Pseudostratified Columnar Epithelium
- Lines the trachea, typically containing ciliated cells aiding in mucus movement.
-
Simple Columnar Epithelium
- Lines the digestive tract, involved in absorption and secretion.
-
Simple Cuboidal Epithelium
- Located in the kidneys, playing a role in secretion and absorption.
-
Simple Squamous Epithelium
- Found in the lungs, facilitating gas exchange due to its thin structure.
