Gel like matrix with three fibers types, : Cells fibroblasts, macrophages, mast cell and some white blood cells.
FUNCTIONS: Provides padding and cushions shocks; insulates; stores energy reserves
LOCATIONS: Deep to the skin (subcutaneous fat); padding around eyeballs, kidneys and other organs
LOCATIONS: Liver, spleen, lymph nodes, red bone marrow
FUNCTIONS: Provides supporting framework (stroma) of soft organs
Dense Regular Connective Tissue
LOCATIONS: Tendons (muscle to bone); ligaments (bone to bone)
FUNCTIONS: Provides firm attachment points; conducts pull of muscles; stabilizes skeleton
Dense Irregular Connective Tissue
LOCATIONS: Dermis; periostea and perichondria; capsules on outside surface of organs.
FUNCTIONS: Provides strength by resisting forces in multiple directions
Elastic Connective Tissue
Dense regular connective tissues containing a high proportion of elastic fibers.
Function: Allows tissues to recoil after stretching; maintains pulsating flow of blood through arteries; aids passive recoil of lungs following inspiration.
Location:Walls of large arteries; within certain ligaments associated with the vertebral column; within the walls of lungs and bronchial tubes.
Fluid Connective Tissues
Formed elements (cells):
-Erythrocytes (red blood cells): transport O2
-Leukocytes (white blood cells): diverse population of different immune cells
-Platelets: cell fragments involved in clotting
Location: contains within blood vessels.
Function :Transports respiratory gases, nutrients, wastes, and other substances.
3 types of cartilages
- is the most abundant cartilage and contains densely packed collagen fibers
contains many flexible and resilient elastic fibers
- consists of interwoven collagen fibers and is very durable and well-suited for shock absorption
