Veterinary Histology: Cells, Epithelium & Connective Tissues

Flashcards summarizing key concepts related to Veterinary Histology focusing on cellular structures, connective tissues, epithelium, and their functions.

Connective Tissue

A primary tissue type that supports, connects, and protects body structures, characterized by abundant extracellular matrix.

Fibroblasts

The most abundant cell type in connective tissue responsible for synthesizing extracellular matrix components.

Macrophages

Cells derived from monocytes that function in phagocytosis and immune response in connective tissue.

Extracellular Matrix (ECM)

The non-cellular component in connective tissue that provides structural and biochemical support to surrounding cells.

Hyaline Cartilage

A type of cartilage that provides support and flexibility, found in joints, trachea, and growth plates.

Endocrine Glands

Glands that secrete hormones directly into the bloodstream or tissues, e.g., the pineal gland.

Simple Epithelium

Tissue consisting of a single layer of cells resting on a basement membrane, includes squamous, cuboidal, and columnar types.

Glycosylation

The process of attaching sugars to proteins, primarily occurring in the Golgi apparatus.

Mitosis

A type of cell division resulting in two identical daughter cells, observed in rapidly dividing cells.

Microfilaments

Components of the cytoskeleton made of actin, providing mechanical support and aiding cellular movement.

Lysosomes

Organelles containing digestive enzymes for breaking down waste and cellular debris.

Serous Membrane

Membranes that line body cavities and produce serous fluid for lubrication.

Fluid Mosaic Model

A model describing the structure of cell membranes, emphasizing the dynamic nature of phospholipids and proteins.

Transitional Epithelium

A type of epithelium that can change shape, found in areas subjected to stretching like the bladder.

Cilia

Microtubule-based structures projecting from the cell surface that assist in movement and sensing environmental changes.
