mast cells
In areolar connective tissue, mast cells are the primary cells responsible for releasing histamine. Histamine is a chemical mediator that plays a crucial role in inflammatory responses and allergic reactions. When tissue is damaged or exposed to allergens, mast cells degranulate and release histamine, leading to increased blood flow and vascular permeability, which facilitates the movement of immune cells to the affected area. This process contributes to the characteristic symptoms of inflammation, such as redness, swelling, and warmth.
connective tissue
The cell type found in connective tissue proper that is close to blood vessels and secretes heparin and histamine is called a mast cell. Mast cells play a crucial role in the immune response and are involved in inflammatory processes. Heparin acts as an anticoagulant, while histamine is involved in promoting blood flow and increasing vascular permeability during allergic reactions.
Fibrous protein
Connective tissue is the tissue group with widely scattered cells. In connective tissue, cells are separated by an extracellular matrix composed of fibers and ground substance. Examples of connective tissue include loose connective tissue, dense connective tissue, and adipose tissue.
Histamine is released by basophils and mast cells in near by connective tissue which is an immune response to foreign pathogens.

Marrow
They are released by basophils and mast cells in nearby connective tissue.
The synovial membrane consists of fibrous connective tissue overlying loose connective tissue. It lines joint cavities and produces synovial fluid to lubricate and cushion the joint surfaces.

Connective Tissue, because it's formed from the same embryonic layer as other connective tissues.

No. They are not connective tissue.
