Q

: Specialized cells embedded in the matrix.

A

Bone Cells (Osteocytes)

30
Q

Composed mostly of intercellular material.

A

Matrix:

31
Q

: Specialized cells embedded in the matrix.

A

Cartilage Cells (Chondrocytes)

32
Q

Specialized cells embedded in the matrix.

A

Tendon Cells (Fibroblasts):

33
Q

Provide strength and support within the matrix.

A

Protein Fibers:

34
Q

The fibers consist of long protein molecules that are embedded in the ground substance. They are produced by the tissue cells which are themselves contained within the matrix.

A

Collagen Fibers

35
Q

is described as an amorphous (shapeless or formless), extracellular material which serves as a diffusion medium in the spaces around the cells and fibers. It plays a major role in determining the physical nature of a connective tissue.

A

Ground substance

36
Q

Elastin molecules form protein fibers which have a yellowish or ivory color to the unaided eye, so we call them “yellow fibers.” In tissue, the elastin molecules often form large “web-like” structures. Elastic fibers are highly elastic and more flexible than collagen. However, they have much less tensile strength.

A

Elastin Fibers

37
Q

Ground substance can range in consistency from liquid, as in blood,

A

where the matrix is “plasma” and the ground substance is actually dilute saltwater, to gel-like, as in cartilage, or to solid, as in bone.

38
Q

are cross-linked together to form rubberlike, elastic fibers. Each elastin molecule uncoils into a more extended conformation when the fiber is stretched and will recoil spontaneously as soon as the stretching force is relaxed.

A

Elastin Polypeptide Chains

Elastin polypeptide chains

39
Q

Young Skin vs. Aged Skin

A

Young Skin: Contains abundant collagen and elastin fibers, fibroblasts, and hyaluronic acid, contributing to its elasticity and firmness.
Aged Skin: Shows reduced collagen and elastin fibers, fewer fibroblasts, and decreased hyaluronic acid, leading to wrinkles and sagging.
