Veterinary Histology Lecture Notes

These flashcards cover key concepts from a Veterinary Histology lecture, focusing on cell biology, tissue types, and organ systems.

What are the three major components of eukaryotic cells?

The cell membrane, the cytoplasm, and the membrane-bound nucleus.

What is the primary function of mitochondria?

To produce ATP (energy) for the cell through Kreb's cycle, oxidative phosphorylation and fatty acid oxidation.

What are the two basic types of Endoplasmic Reticulum(ER)?

Rough Endoplasmic Reticulum (rER) and Smooth Endoplasmic Reticulum (sER)

What is the main function of the Golgi complex?

Process transported substances from ER, polysaccharide synthesis, modification of secretory products, and packaging/storage of secretory products.

What is the function of lysosomes?

To act as the cellular digestive system by containing hydrolytic enzymes

What are the main components of the cytoskeleton?

Microfilaments, intermediate filaments, and microtubules.

Which cytoskeleton component is composed of the protein actin?

Microfilaments

What are the two types of junctions for cell attachment and communication?

Adhering junctions and impermeable junctions

Name the type of special epithelia that contains myofibrils and contractile elements responsible for expression of secretory products into ducts.

Myoepithelium

What are the two categories of glands acording to morphologic characteristics?

Unicellular glands and multicellular glands

What are the components of connective tissues?

Cells, intercellular fibers, and amorphous ground substance.

Name three types of cartilage.

Hyaline cartilage, elastic cartilage, and fibrocartilage.

What are the cellular components of bone?

Mesenchymal cells, osteoblasts, osteocytes and osteoclasts

What are the two major types of bone?

Woven bone and lamellar bone.

Describe the function of leukocytes.

Migrate into connective tissue from blood vessels; defend the organism against bacterial invasion or the presence of foreign material.

What are the two main classes of leukocytes?

Agranulocytes and granulocytes

What are the essential stages of mitosis?

Coiling, orientation, movement and uncoiling (COMU).
