What tissue composes epidermis?

The epidermis is composed of multiple layers of epithelial cells, including keratinocytes, melanocytes, and Langerhans cells. It is the outermost layer of the skin and serves as a protective barrier against environmental factors.


Which tissues are classified as connective tissue proper?

Connective tissue proper is classified into two main categories: loose connective tissue and dense connective tissue. Loose connective tissue includes types like areolar, adipose, and reticular tissue, which provide support, elasticity, and nutrient storage. Dense connective tissue is further divided into dense regular (e.g., tendons and ligaments) and dense irregular (e.g., dermis of the skin) tissues, which offer strength and resistance to stress. Together, these tissues serve various functions, including support, protection, and storage within the body.


What is the function of hyaluronic acid in ground substance?

It serves as the viscous fluid of connective tissue proper.


Is myelin a connective tissue?

No, myelin is not a connective tissue. Myelin is a lipid-rich material that forms a protective sheath around nerve fibers in the central and peripheral nervous systems. It is essential for the proper functioning of the nervous system by insulating and speeding up the transmission of nerve impulses.


What do the heartstrings do?

Heartstrings, also known as chordae tendineae, are strong fibrous cords that attach the valves of the heart to the muscles in the heart wall. They help to prevent the valves from collapsing back into the heart chambers when they close, ensuring proper blood flow through the heart.

Are the chordae tendinae and papillary muscles in a pig's heart?

Yes, chordae tendinae and papillary muscles are present in a pig's heart. Chordae tendinae are fibrous cords that connect the papillary muscles to the valves of the heart, providing support and preventing backflow of blood. Papillary muscles contract to tighten the chordae tendinae during ventricular contraction, aiding in the proper function of the heart valves.


Which layer of the basement membrane of epithelial tissues is produced and secreted by cells of the underlying connective tissue?

The lamina densa layer of the basement membrane is produced and secreted by cells of the underlying connective tissue. This layer is primarily composed of collagen type IV fibers and serves as a sturdy foundation for the overlying epithelial cells.


What distinguishes cartilage from connective tissue proper?

Cartilage is a specialized type of connective tissue that is tough and flexible, providing support and cushioning in the body. It is composed of chondrocytes and extracellular matrix, mainly collagen and proteoglycans. Connective tissue proper, on the other hand, includes loose and dense connective tissue that provides structural support and flexibility to organs and tissues.


What are the 3 major groups of connective tissue?

Epithelial, muscle, and nervous. Disagree- the 3 subgroups are: loose, dense, and connective tissue with special properties. Subgroups within dense are: dense irregular, in which the extracellular fibers are interwoven in disordered fashion, and dense irregular, in which the extracellular fibers are in parallel bundles. Subgroups in the special properties connective tissue are named to indicate the identifying feature, such as mucous connective tissue, elastic connective tissue or reticular connective tissue.


What forms the soft packaging around organs?

Areolar connective tissue proper


Does a complex sentence have to have a connective in it?

Not always but it makes you sound more proper and correct


Why would areolar tissue be considered the prototype for connective tissue proper?

Areolar tissue is considered the prototype for connective tissue proper because it exhibits the most typical features of connective tissue, such as a loose arrangement of cells and fibers in a gel-like matrix. It also serves as a functional and structural support for organs and helps in holding them in place.


What is the role of papillary muscle?

Papillary muscles in the heart are responsible for anchoring the chordae tendineae, which are fibrous cords that attach to the heart valves (mitral and tricuspid). Their main role is to prevent the valves from prolapsing into the atria during ventricular contraction and to ensure proper valve closure, which helps maintain efficient blood flow through the heart.


What kind of body tissue is both living and non living?

connective tissue proper


Which part of the intrinsic conduction system sends fibers along the lateral walls of the ventricles towards the base and stimulates the papillary muscles?

The moderator band, also known as the septomarginal trabecula, sends fibers along the lateral walls of the ventricles towards the base and stimulates the papillary muscles. It helps coordinate the contractions of the ventricular walls and the papillary muscles to facilitate proper valve function.
