Histo Lec - M6 Cartilage, Osseous, Hematopoietic Tissue Flashcards
is a resilient connective tissue composed of cells embedded in an extracellular matrix that is gel-like and has a rigid consistency.
Cartilage
the most common cartilage in the body. It is bluish-white and translucent.
Hyaline cartilage
vascularized connective tissue sheath surrounding cartilage (except in case of articular cartilage).
Perichondrium
immature cartilage cells. Secrete extracellular matrix,
Chondroblasts
mature cartilage cells that are embedded in rigid extracellular matrix.
Chondrocytes
Similar to hyaline cartilage except, matrix is impregnated with fibers, yellow in color
Elastic cartilage
is an irregular, dense, fibrous tissue with thinly dispersed, encapsulated chondrocytes. No perichondrium, so it blends with adjacent connective tissue.
Fibrocartilage
a major structural and supportive connective tissue of the body. It forms the rigid part of the bone organs that make up the skeletal system.
Osseous Tissue
are formations characteristic of mature bone and take shape during the process of bone remodeling, or renewal
Osteons
fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products
Blood
is a yellowish liquid component of blood that holds the blood cells in whole blood in suspension
Blood plasma
Known for their bright red color, red cells are the most abundant cell in the blood,
The Erythrocytes
They are the cells of the immune system involved in defending the body against both infectious disease and foreign materials
Leukocytes or White Blood Cells
Extracellular matrix of cartilage is mainly?
Collagen and/or elastic fibers, proteoglycans, and water.
Cartilage is composed of specialized cells that produce a large amount of collagenous extracellular matrix, abundant ground substance that is rich in proteoglycan and elastin fibers.
Chondrocytes
classification of cartilage
hyaline cartilage, elastic cartilage and fibrocartilage.
This sort of growth of cartilage the extracellular matrix is secreted into spaces between the cells.
interstitial growth
This growth is a layer of chondroblasts can lay down matrix at the outer edge of a mass of cartilage.
appositional
is a major structural and supportive connective tissue of the body. It forms the rigid part of the bone organs that make up the skeletal system.
Osseous tissue
Functions of Osseous Tissue
1.Support for muscles, organs, and soft tissues
2.Leverage and movement
3.Protection of vital organs, e. g. heart
4.Calcium phosphate storage
5.Hemopoiesis or the formation of blood cells
is the fundamental functional unit of compact bone
The osteon or Haversian system
is a connective tissue that has a fluid matrix, and no fibers.
blood
fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products.
blood
is a yellowish liquid component of blood that holds the blood cells in whole blood in suspension.
The Blood Plasma
Plasma’s total blood volume?
55%
serves as a transport medium for delivering nutrients to the cells of the various organs of the body and for transporting waste products derived from cellular metabolism to the kidneys, liver, and lungs for excretion.
Plasma
is blood plasma without clotting factors
blood serum
Known for their bright red color, these cells are the most abundant cell in the blood, accounting for about 40 to 45 percent of its volume.
Erythrocytes
Production of red blood cells is controlled by hormone produced primarily by the kidneys.
erythropoietin
The red blood cell survives on average only ____ days.
120 days
Special protein in blood that helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled
hemoglobin
Erythrocytes are efficient transporters of gases because of the following histological features:
- Biconcave form gives 20% - 30% greater surface area than the spherical form.
- Absence of nucleus allows more spaces for gases.
- Round edges and resilient elastic structure protects the erythrocytes from injury and allow them to bend at bifurcations in capillaries.
are cell fragments which circulate within the blood
Thrombocytes or Platelets
Life span of platelets
10 days
