What tissue has many cells among network of reticular fibers?
What tissue has many cells among network of reticular fibers?
loose connective tissue
What is reticular connective tissue composed of?
A connective tissue that contains a large network of reticular fibers is called a reticular connective tissue. The reticular fibers are made up mainly of type III collagen (100-150 nm in diameter) synthesized by special fibroblasts, reticular cells.
What are the similarities and differences between reticular and loose connective tissue?
6 pts Loose tissue Reticular tissue Both Has elastic fibers Has reticular fibers Has fibroblasts Contains ground substance Regular, mesh-like appearance under microscope Contains ground substance Has elastic fibers Has fibroblasts Has reticular fibers Variable appearance.
What are the differences between the reticular collagen and elastic fibers?
Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column. Reticular fiber is also formed from the same protein subunits as collagen fibers; however, these fibers remain narrow and are arrayed in a branching network.
What color are reticular fibers?
Reticular fibers are usually observed as a delicate meshwork of fine fibrils stained black by the silver impregnation method. They usually underlie the epithelium and cover the surface of such cells of muscle cells, adipose cells and Schwann cells.
Does blood have reticular fibers?
Although reticular fibers are widely distributed in the body, reticular tissue is limited to certain sites. It forms a labyrinth-like stroma (literally, “bed or “mattress”), or internal framework, that can support many free blood cells (largely lymphocytes) in lymph nodes, the spleen, and red bone marrow.
What are characteristics of reticular fibers?
6.2. 1 Reticular Fibers and Basement Membranes. Reticular fibers are highly branched, delicate, argyrophilic fibers that stain with ammoniacal silver solutions. Electron microscopic studies have shown that they are young collagen or a small bundle of collagen fibrils.
What is meant by reticular fibers?
Reticular fibre, in anatomy, fine fibrous connective tissue occurring in networks to make up the supporting tissue of many organs. The reticular fibres are composed of randomly oriented collagenous fibrils lying in an amorphous matrix substance.
Where are reticular cells found?
Reticular cells provide structural support, since they produce and maintain the thin networks of fibres that are a framework for most lymphoid organs. They are found in many tissues including the spleen, lymph nodes and lymph nodules.
How are reticular fibers formed?
In almost all instances, reticular fibers and tissue are produced by fibroblasts. The exception are lymphoid organs and structures, in which reticular cells are responsible for the synthesis. They are a special type of fibroblasts with a variety of additional functions.
Is reticular fiber a protein?
Reticular fibers, the third type of protein fiber found in connective tissues, consist of thin strands of collagen that form a network of fibers to support the tissue and other organs to which it is connected.
Are reticular fibers in cartilage?
Type II – found in hyaline and elastic cartilage and in vitreous body of eye. Type III – found in reticular fibers, healing wounds, smooth muscle, and fetal skin. Type V – found in placental basal laminae, tendon, and muscle sheaths. Reticular fibers – form network of fibers.
Is reticular tissue vascular?
The rodent endometrial stroma consists of loosely arranged reticular connective tissue with many small polyhedral cells. The myometrium is composed of an inner circular layer and outer longitudinal layer of smooth muscle fibers separated by loose, highly vascular connective tissue, the stratum vasculosum.
Which is the most vascularized connective tissue?
Connective tissue Is found throughout the body and it supports or binds other tissues and provides for the metabolic needs of the body organs. Connective tissue, with the exception of cartilage, is highly vascularized and well nourished.
Which type of tissue has the poorest blood supply?
cartilage connective tissue
What type of tissues have the best blood supply?
Most connective tissues have a good blood supply but some do not. Numerous cell types are found in connective tissue. Three of the most common are the fibroblast, macrophage, and mast cell.
What membrane is more commonly called the skin?
The skin is an epithelial membrane also called the cutaneous membrane. It is a stratified squamous epithelial membrane resting on top of connective tissue.
How does blood tissue support the body?
Functions of Connective Tissues Specialized cells in connective tissue defend the body from microorganisms that enter the body. Transport of fluid, nutrients, waste, and chemical messengers is ensured by specialized fluid connective tissues, such as blood and lymph.
What are the 4 tissue types?
There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue.
Where is adipose tissue found in the body?
Adipose tissue is commonly known as body fat. It is found all over the body. It can be found under the skin (subcutaneous fat), packed around internal organs (visceral fat), between muscles, within bone marrow and in breast tissue.
What is the job of the nerve tissue?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.
What are the characteristics of nerve cell?
The distinguishing characteristic of nerve cells is their specialization for intercellular communication. This attribute is apparent in their overall morphology, in the specialization of their membranes for electrical signaling, and in the structural and functional intricacies of the synaptic contacts between them.
