Connective tissue shorter ver

Stem cells are classified by what?

Stem cells are classified by the tissues they create

totipotent

pluripotent

multipotent

immature/forming cells

-blasts

stem cells that divide and secret ground substance and fibers

mature cells

-cyte

mature cells that maintain the matrix

Characteristics of loose connective tissue:

* Areolar: Loosely woven collagen/elastin fibers; surrounds vessels and supports epithelial layers.

* Adipose: Dominated by lipid-storing adipocytes for energy storage and insulation.

* Reticular: Mesh-like supportive network for lymphatic organs

Characteristics of dense connective tissue

• Dense Regular: Parallel collagen fibers providing strength in one direction (e.g., tendons and ligaments)

• Dense Irregular: Randomly woven collagen fibers that resist multidirectional stress (e.g., dermis of skin)

what are the wandering cells/immune cells?

Macrophages - debris and bacteria

Mast cells - release histamine during allergic responses

what is cartilage and types of cartilage?

Semisolid, flexible matrix; contains chondrocytes residing in small spaces called lacunae

* Hyaline Cartilage: Most common type; smooth to reduce joint friction.

* Fibrocartilage: Packed with visible collagen fibers for shock absorption in weight-bearing areas.

* Elastic Cartilage: Rich in elastic fibers for tissues requiring shape flexibility

different types of bone tissue

Hardest connective tissue; rigidity comes from calcium and phosphate

* Compact Bone: Dense, outer protective layer

* Spongy Bone: Porous and stores bone marrow.

what is and types of fluid connective tissue

Liquid matrix (plasma) with few to no fibers, specialized for transport

• Erythrocytes: Red blood cells that transport oxygen and CO2

• Leukocytes: White blood cells involved in immune defense.

• Thrombocytes: Platelet fragments that prevent excessive bleeding through clotting.

what is Marfan syndrome

A genetic disorder affecting proteins that build elastic fibers within the ground substance^[13]. Symptoms include long limbs/fingers, scoliosis, weak joints, and tall/thin stature
