Study Notes
Classification of Connective Tissue
- Connective tissues are categorized based on the type of ground substance (matrix).
- Three main types:
- Connective tissue proper: Contains a gelatinous or semi-solid ground substance.
- Vascular or fluid connective tissue: Features a fluid or liquid ground substance.
- Skeletal or supporting connective tissue: Composed of a solid or rubbery ground substance.
Histology of Loose and Dense Connective Tissues
- Loose connective tissue: Characterized by a flexible structure, allowing for the support and cushioning of organs.
- Dense connective tissue: Known for its tightly packed fibers, providing strength and resistance to stretching forces.
Overview of Cartilage
- Cartilage is a resilient and flexible connective tissue essential for various body structures.
- Three types of cartilage:
- Hyaline cartilage: Provides a smooth surface for joint movement and flexibility.
- Elastic cartilage: Contains more elastin fibers, enhancing flexibility; found in structures like the ear.
- Fibrocartilage: Contains dense fibers, making it tough and supportive; found in intervertebral discs.
Muscular Tissue
- Muscular tissues are composed of highly cellular and well-vascularized cells responsible for body movement.
- Muscle cells contain myofilaments composed of actin and myosin, facilitating contraction.
- Three types:
-
Skeletal muscle:
- Cylindrical shape and striated appearance.
- Multinucleated with peripheral nuclei.
- Voluntary control, fatigue quickly, found in limbs and body wall.
-
Smooth muscle:
- Spindle-shaped and unstriated.
- Uninucleated with central nuclei.
- Involuntary action, fatigue-resistant, located in gastrointestinal tract (GIT) and glands.
-
Cardiac muscle:
- Cylindrical and striated, with branched fibers.
- Uninucleated and central nuclei present.
- Involuntary action, fatigue-resistant, found in the heart wall.
- Intercalated disks are present, facilitating communication between cells.
-
Skeletal muscle:
