Question 4

What is Mesenchyme

Answer 4

Mesenchyme is a type of animal tissue comprised of loose cells embedded in a mesh of proteins and fluid, called the extracellular matrix. … Mesenchyme directly gives rise to most of the body’s connective tissues, from bones and cartilage to the lymphatic and circulatory systems

Question 5

Mast cell

Answer 5

Mast cell, tissue cell of the immune system of vertebrate animals. Mast cells mediate inflammatory responses such as hypersensitivity and allergic reactions. … Upon stimulation by an allergen, the mast cells release the contents of their granules (a process called degranulation) into the surrounding tissues.

Question 6

Adipocyte

Answer 6

CT cell that stores fat

Question 7

Leukocyte

Answer 7

aka WBC. Key to immunity

Question 8

Plasma cell

Answer 8

A type of immune cell that makes large amounts of a specific antibody. Plasma cells develop from B cells that have been activated. A plasma cell is a type of white blood cell.

Question 9

Macrophages

Answer 9

derived from monocytes. WBC that eats foreigners and cellular debris by phagocytosis

Question 10

Fibroblast

Answer 10

A fibroblast is a type of biological cell that synthesizes the extracellular matrix and collagen, produces the structural framework (stroma) for animal tissues, and plays a critical role in wound healing. Fibroblasts are the most common cells of connective tissue in animals.

Question 34

What is Hyaline cart?

Answer 34

Hyaline cartilage is the glass-like (hyaline) but translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea.

Hyaline cartilage provides mechanical support for the respiratory tree, nose, articular surfaces, and developing bones

Question 36

What is Fibrocatalige?

Answer 36

Fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions. It owes its inflexibility and toughness to the former of these constituents, and its elasticity to the latter. It is the only type of cartilage that contains Type I collagen in addition to the normal type II.
