Cytology
What is Cell membrane (Plasmalemma)
Found in the trachea and bronchi
What is Pseudostratified columnar epithelium?
All bones in the skull except the bones of the base of the skull form this way
What is Intramembranous ossification?
What are astrocytes?
What is the rouleaux formation?
Lamina lucida, Lamina densa, basal lamina, and reticular (sub basal) lamina are all parts of this membrane
What is the Basement membrane?
Cartilage that is surrounded by perichondrium( which is composed of an outer fibrous layer made of collagen fibers and fibroblasts and inner layer made of chondroblast) found in places like the nose
What is Hyaline cartilage?
Also known as motor nerve fibers. They leave the spinal cord on the ventral root
What is Efferent nerve fibers?
Connective tissue that fills the space between the AV opening and the base of aorta. It is made of different tissues between different species ex: dense irregular CT in pigs and cats, fibrocartilage in dogs, hyaline cartilage in horses, bone in ox.
What is the fibrous triangle?
Is basophilic and has numerous pores in its two concentric membranes
What is nuclear envelope?
Found between the secretory cell and basement membrane and help push the secretory products to the duct system
What is myoepithelial cells?
These come from fibroblast and are composed of elastin protien and covered by glycoprotien (fibrillin)
What is Elastic fibers?
These activate for protein synthesis to help repair damaged nerve cells. Once healed, they migrate back to the neuronal cell body.
What are Nissl Bodies (rER)?
In horses these leucocyte look like mulberry-like. They also play a role in allergic and anaphylactic reaction and in parasitic infestation.
What is eosinophils?
Also known as Brush border
What is microvilli?
Made up of dense protein lines that connect the actin filaments of the I band in skeletal muscle
What is the Z line?
They are the most predominant fiber and are found in tendon, ligament, and organ capsules.
What is collagen fibers?
Cerebrospinal fluid is produced here; the fluid then travels through the lateral aperture into the subarachnoid space.
What are continuous capillaries?
Allows the age to be observed of cells like cardiac muscles, liver cells, and nerve cells
What is Lipofuscin?
this muscle have no regenerative capacity after birth. Once the fibers are damaged they are replaced by profileration of connective tissue and form a scar
What is cardiac muscles?
Wrap around endothelial cells lining small blood vessels and regulate blood flow. They also have the ability to transform into other cells during the healing process.
What is Pericytes?
A single layer of piriform cells that send ramified dendrites into the molecular layer and axons into the white matter
What are Purkinje cells
This marrow is actively involved in hematopoiesis. Nutrient arteries provide the necessary nutrients for the production of cells here.
