**Identify the Types of Cartilage and Muscle**  **Take note of the Smooth Muscle of the stomach. Take note of the single nucleus, in a spindle shaped fiber.** **Identify Dog blood smear from a Horse blood smear** **Characteristics of Blood Smear in;** **Horse --** Formation of stacking in Horses red blood cells. Remember that Rouleaux formation is only in healthy horse (and in some cats). Not seen in Cattle and Dog **Chicken --** (not sure) **Dog** -- (not sure) **Reminder: Central Pallor** -- Only in Dogs. Not found in Cats, Bovine and Equine **Spongy Bones --** **What do you call the Opening of Spongy bone** -- Trabeculae **Epimysium, Perimysium & Endomysium** **Hyaline vs Elastic Cartilage** **Hyaline cartilage** The most common type of cartilage in the body, hyaline cartilage is tough but slightly flexible. It\'s made up of a matrix of closely packed collagen fibers, and is found in the following locations:  Lining joints  Capping the ends of bones  Inside bones, where it serves as a center of bone growth  In the walls of the respiratory tracts, including the nose, larynx, trachea, and bronchi  **Elastic cartilage** Also known as yellow cartilage, elastic cartilage is the most flexible type of cartilage in the body. It\'s made up of collagen and elastic fibers, which give it a stiff yet elastic quality. Elastic cartilage is found in the following locations:  The pinna of the ear  The walls of the auditory and eustachian canals  The larynx   The epiglottis **Identify types of WBC (to be check kay Doc)** **Animal Species** **Erythrocyte** **Neutrophil** **Eosinophil** **Basophil** -------------------- ------------------------------------ ------------------------------------ ------------------------- --------------------------------------------------- **Canine** **Central pallor / Normal canine** **3 -- 5 segments of lobed** **5%** **1% last of WBC** **Feline** **Biconcave Disc** **1^st^ line of Defense / Difera** **Parasitic, Toxicity** **Equine** **Bovine** **Smaller Size** **Present in Inflammatory** **Ovine** **Smaller Size** **Present but not characterized** **Caprine** **Smaller Size** **Present in Inflammatory but not characterized** **Porcine** **Poikilocytosis** **Present in Inflammatory** **The Animal nucleated RBC --** Avian **Where is the location of Hematopoiesis? --** Spongy Bones / the spongy tissue inside of your bones called bone marrow In adult animals, **hematopoiesis occurs** in the bone marrow, the central cavity of bones. (Pero base kay Doc. ay (Bone marrow -- Young / Flat Bone -- Adult) **What do you call the Myofibrils of the Smooth Muscle(?) --** **Give the cell of Muscle fiber --** Myocytes **Only multinucleated muscle** -- Skeletal muscle fibers **Layer of the bone that is involve in osteogenesis**? -- The periosteum\'s inner cambium layer, also known as the osteogenic layer, is involved in osteogenesis. **Mode of cell growth of Cartilage (**Appositional & Interstitial**) & Bone (**Appositional method only**)** **Appositional growth of bone starts at the periosteum**, a layer of connective tissue and blood vessels that encases the bone. **Least circulating white blood cells in blood** -- Basophils **Bonus Questions:** **True or False** Red Blood Cells are **LARGER** than mammals? Answer: **False** **Blood supply enter the bone through the?** -- Blood vessels enter the bone through the nutrient foramen, which are small openings in the diaphysis of the bone.
