What else can I help you with?
What has the thickest tunica media?
Large elastic arteries, such as the aorta and pulmonary trunk, have the thickest tunica media. This layer is predominantly composed of smooth muscle cells and elastic fibers, allowing these arteries to expand and recoil in response to changes in blood flow and pressure.
What connective tissue forms protective layer of eye?
The connective tissue that forms the protective layer of the eye is called the sclera. This tough, white outer layer helps maintain the shape of the eye and provides attachment points for the eye's muscles.
What type of epithelial tissue forms the dermis of the skin?
The dermis of the skin is mainly composed of dense irregular connective tissue. This tissue is rich in collagen and elastic fibers, providing strength, support, and elasticity to the skin.
What is to fibers as cuticle is to wax?
Hair. A cuticle is the outer layer of hair, just as wax is the outer layer of a fiber at times.
What type of connective tissue is reticular made of?
Reticular tissue is a type of connective tissue that is composed of reticular fibers, which are a type of thin, branching fibers made of collagen. It forms a mesh-like network that provides structural support in organs such as lymph nodes, bone marrow, and spleen.
What tissue contains loose arrangement of the elastic and collagen fibers?
Reticular layerpapillary layer and reticular layerhave collagenic fibers, however most of abundant area would be the epidermis (as a whole)Unfortunately for them, but fortunately I'm here for you, the answer is Dermis. The dermis is composed of connective tissue containing mainly of collagen fibers and also elastic and reticular fibers. Also, contains connective tissue cells, blood vessels, sweat and sebaceous glands, hair follicles, nail root, nerve endings, and muscular tissues. WE WANT CORRECT ANSWERS ...(ANSWERS.COM) :)
What skin region is the site of elastic and collagen fibers?
Reticular layer
Which layer of skin is composed mainly of connective tissue with collagen and elastic fibers?
The reticular layer of the dermis
What dermal layer is primarily responsible for strength of skin?
collagen fibers and resilient elastic fibers
Is sclera pleural?
No, the sclera is actually an opaque, white, fibrous layer that protects the eye. It is not a space, it contains collagen and elastic fibers.
Where Elastic fibers are absent in case of blood vascular system?
The capillaries are the only blood vessels without elastic tissue. This is so that the vessel walls are as thin as possible to reduce the diffusion distance (for gases and waste products). Veins do contain a layer of elastic tissue is their walls, but this is a very thin layer (when compared to arteries).
What are some chemical properties of the Dermis?
Collagen fibers makes up 75% of the dermis, which is the inner layer of skin that protects the body from physical stress, it also contains elastic fibers, and ground substances.
What are the different layers of the blood vessel walls called?
1.Tunica intima (Latin for innermost coat) is the innermost layer. Includes the endothelial lining and an underlying layer of connective tissue with a variable number of elastic fibers. In arteries the outer margin of the tunica intima cointains a thick layer of elastic fibers called the internal elastic membrane.2.Tunica media (Latin for middle coat) is the middle layer. Contains concentric sheets of smooth muscle tissue in a framework of loose connective tissue. The collagen fibers bind the tunica media to the tunica intima and tunica externa. Commonly the thickest layer in the wall of a small artery, the tunica media es separated from the surrounding tunica externa by a thin band of elastic fibers called external elastic membrane. The smooth muscle cells of the tunica media encircle the endothelium linning the lumen of the blood vessel. When these smooth muscles contract, the vessel decreases in diameter; when they relax, the diameter increases. Large arteries also contain layers of longitudinally arrranged smooth muscle cells.3.Tunica externa (Latin for outside coat) or tunica adventitia (Latin for coat that comes first) is theoutermost layer. Forms a connective tissue sheath. In arteries, this layer contains collagen fibers with scattered bands of elastic fibers. In veins, it is generally thicker than the tunica media and contains networks of elastic fibers and bundles of smooth muscle cells. The connective tissue fibers of the tunica externa typically blend into those of adjacent tissues, stabilizing and anchoring the blood vessel.
Why is the dermis elastic and spongy?
The dermis, the layer just below the epidermis, is made up of collagen, elastin fibers, and blood vessels. Together they make your skin spongy and plump.
The second layer surrounding the lumen?
The second layer surrounding the lumen in blood vessels is the tunica media. It is composed of smooth muscle cells and elastic fibers, allowing it to contract and expand to regulate blood flow and pressure.
What is a vessel with a thick layer of smooth muscle and elastic fibers that allow for expansion?
An artery is a vessel with a thick medial layer, consisting of smooth muscle to allow for constriction or dilation in order to control blood flow through the vessel.
Compare the strength of arterial walls and capillary walls?
arterial walls has smooth muscle and elastic fibers (strong and flexible) and capillaries are made up of a single layer of endothelial cells (thin).
