Study Notes

Nervous Tissue and Connective Tissue

  • Nervous tissue is primarily composed of neurons and does not predominantly consist of collagen fibers.
  • Connective tissue typically contains a significant amount of matrix and collagen fibers, providing strength and support to various structures.

Epithelial Tissue Characteristics

  • Dense microvilli in simple columnar epithelium enhance absorption in the digestive tract.
  • Simple squamous epithelium forms the walls of air sacs in the lungs for efficient gas exchange.
  • Stratified squamous epithelium features multiple layers with cuboidal basal cells and flat surface cells, offering protection against abrasion.

Tissue Repair and Inflammation

  • Inflammation initiates tissue repair by causing capillaries to dilate and increase permeability, allowing immune cells to reach the injured area.

Types of Glandular Epithelia

  • Goblet cells in pseudostratified ciliated columnar epithelium secrete mucus, aiding in protection and lubrication.
  • Merocrine glands secrete substances without altering the cell structure, in contrast to cell rupture found in other gland types.

Muscle and Connective Tissue Features

  • Smooth muscle cells possess a central nucleus and lack striations, displaying a unique structure suited for involuntary movements.
  • Fibrocartilage serves as shock-absorbing pads between vertebrae, characterized by high tensile strength and the presence of collagen fibers.

Extra Facts on Bone and Cartilage

  • Bone tissue includes lacunae, calcium salts, and blood vessels, differentiating it from other tissues.
  • Hyaline cartilage is distinct for having collagen fibers that are typically not visible, offering a smooth surface.

Function and Structure of Various Tissues

  • Adipose tissue functions primarily in nutrient storage, while also providing insulation and padding for organs.
  • Endocrine glands, such as the thyroid, release hormones directly into the bloodstream, without ducts.

Histological Insights

  • Epithelial tissues display polarity, having distinct apical and basal surfaces crucial for their functionality.
  • Transitional epithelium can morphologically resemble either stratified squamous or cuboidal epithelium depending on the bladder's state.

Regeneration and Healing

  • Cartilage heals slower than bone due to its reduced blood supply, leading to more gradual recovery from injuries.
  • Edema, or swelling, occurs when areolar tissue absorbs excess fluid during inflammation, contributing to tissue homeostasis.

Miscellaneous Tissue Facts

  • Intercalated discs, found in cardiac muscle, are essential for cell cohesion and communication.
  • Elastic cartilage provides structural integrity and adaptability, found in areas like the external ear and large arterial walls.
