What type of connective tissue is found in the muscle in the walls of arteries?
What type of connective tissue is found in the muscle in the walls of arteries?
What type of connective tissue is found in the muscle in the walls of arteries?
The intima is a layer of endothelial cells and connective tissue which covers the luminal surface of the arteries. The media consists of connective tissue (tissue full of collagen, elastin, and other elastic fibers) and smooth muscle cells. Smooth muscle cells are able to contract and relax.
How do you distinguish generally between epithelial and connective tissue?
How do you distinguish generally between epithelium and connective tissue? Epithelium is more cellular than connective tissue. The nuclei in many of the simple epithelial tissues are aligned. In connective tissue there are more non-cellular structures present such as fibers or a matrix.
What is the outer connective tissue layer that envelops some hyaline cartilage?
The perichondrium is a dense layer of fibrous connective tissue that covers cartilage in various parts of the body.

What are three traits of smooth muscle?
Smooth Muscle Characteristics
- Smooth muscle cell shape. The smooth muscle cell is fusiform in shape.
- The filaments.
- Single nucleus.
- Elasticity.
- Contractility.
- Lack of sarcomeres.
- Lack of a tropomyosin complex.
What is the relationship between epithelial tissue and connective tissue in the body?
Epithelial tissues act as coverings, controlling the movement of materials across their surface. Connective tissue binds the various parts of the body together, providing support and protection. Muscle tissue allows the body to move and nervous tissues functions in communication.
What type of fiber is embedded in a loose connective tissue?
collagen
1: Loose connective tissue: Loose connective tissue is composed of loosely-woven collagen and elastic fibers.
Which of the connective tissue fibers imparts the greatest strength?
Which of the connective tissue fibers imparts the greatest strength? plasma.
What is the function of the highlighted tissue?
Question: The function of the highlighted tissue, along with four others that form a ring at the junction of the oral cavity and oropharynx and at the junction of the nasal cavity and nasopharynx, is to participate in responses against inhaled or ingested substances.
What are the four characteristics of smooth muscle?
Four characteristics define smooth muscle tissue cells: they are involuntarily controlled, not striated, not branched, and singly nucleated. The unconscious regions of the brain control visceral muscle through the autonomic and enteric nervous systems. Thus, visceral muscle is involuntarily controlled.
What are the three main components of connective tissue?
Components of connective tissue All forms of connective tissue are composed of (1) extracellular fibres, (2) an amorphous matrix called ground substance, and (3) stationary and migrating cells. The proportions of these components vary from one part of the body to another depending on the local structural requirements.
Is epithelial tissue a connective tissue?
Epithelium (/ˌɛpɪˈθiːliəm/) is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs.
What type of epithelial tissue is found in blood vessels?
Simple squamous epithelium
Types of Epithelial Tissue
| Epithelial Tissue Cells | |
|---|---|
| Cells | Locations |
| Simple squamous epithelium | Air sacs of the lungs and the lining of the heart, blood vessels and lymphatic vessels |
| Simple cuboidal epithelium | In ducts and secretory portions of small glands and in kidney tubules |
What are five general characteristics of epithelial tissue?
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are cellularity, polarity, attachment, vascularity, and regeneration.
What are 3 types of connective tissue?
The three types of connective tissue fibers are:
- Collagen fibers – most are type I collagen (most abundant protein in the body)
- Elastic fibers – contain elastin and fibrillin.
- Reticular fibers – contain type III collagen.
Where is epithelial tissue located?
Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.
What are the 5 characteristics of epithelial tissue?
Despite there being many different types of epithelial tissue all epithelial tissue have just five characteristics, these are cellularity, polarity, attachment, vascularity, and regeneration. Cellularity as the name suggests means that the epithelium is made up almost entirely of cells.
