Fibroblasts.
Connective tissues.
The hypodermis contains connective cells or tissues directly under the skin.
The most common cells found in connective tissues are fibroblasts. These cells are responsible for producing and maintaining the extracellular matrix components such as collagen, elastin, and ground substance, which provide support and structure to the tissue.
sceletal muscle tissue
Tissues. Cells with similar functions and structures come together to form tissues, which are the building blocks of organs and body structures. Examples of tissues include muscle tissue, nerve tissue, and connective tissue.
No, skeletal muscle tissue is composed primarily of skeletal muscle cells, which are a type of muscle tissue. Other types of body tissues like epithelial, connective, and nervous tissue are not typically found within skeletal muscle.
The nervous system is made of neurons (cells) and their supporting connective tissues.
Fibroblasts
Connective tissue is not lined with epithelial cells.
Connective tissues are characterized by having a great deal of space between cells, secretion of matrix, and originating from mesenchyme. Examples of connective tissues include loose connective tissue, dense connective tissue, cartilage, bone, and blood.
No, nerve tissues are made up of specialized cells called neurons that transmit electrical signals. These cells are surrounded by other types of cells called glial cells that provide support and protection. Collagen is a type of protein found in the extracellular matrix of connective tissues, not in the intercellular spaces of nerve tissues.
Yes, most connective tissues arise from mesenchyme, an embryonic tissue. Mesenchyme gives rise to fibroblasts, which then differentiate into various types of connective tissue cells and produce the extracellular matrix. However, some specialized connective tissues like blood and lymph do not directly arise from mesenchyme.
