Types Connective Tissue
Connective tissue proper
Cartilage
Bone
Blood
All Connective tissue arise from
mesenchyme
(embryonic tissue)
Functions of Connective Tissue
Binding and support
Protection
Insulation
Transportation
Structural Elements of Connective Tissue
Ground substance / matrix(gel-like fluidsurrounding fibers and cells)
Fibers
Cells
Types of fibers
Collagen
Elastic
Reticular
Description of Areolar CT
Gel like matrix with all three fiber types; fibroblasts,macrophages,mast cells and some white blood cells.
Function of Areolar CT
Wraps and cushions organs; plays important role in inflamation; holds and conveys tissue fluid.
Location of Areolar CT
Widely distributed under epithelia of body ;forms lamina proper of mucous membranes; packages organs; surrounds capillaries
Function of Adipose CT
Insulates the body and stores excess nutrients
Strongest and largest of the three fiber types
Found in bones and skin
Collagen
Able to stretch and recoil
Help structurally support things
Elastic
Internal framework for certain organs
Reticular
Location of Adipose CT
Found throughout entire body - deep to the skin
Description of Adipose CT
Loose connective tissue
Fat tissue
Adipocytes are
fat cells
Description of Reticular CT
Loose connective tissue
Filled with reticular fibers
Location of Reticular CT
Found in lymphatic organs and the liver
Description of Dense Regular CT
Dense connective tissue
Collagen fibers run parallel to each other
Function of Dense Regular CT
Resist tension and pulling forces in one direction
Location of Dense Regular CT
Found in tendons (attach muscle to bone) and ligaments (attach bone to bone)
Description of Dense Irregular CT
Dense connective tissue
Not running parallel to each other
Function of Dense Irregular CT
Resists tension from several directions
Location of Dense Irregular CT
Found in dermis (deep layer of your skin) and joint capsules (wherever you have a place where two or more bones meet you have a capsule - space between your bones)
Elastic Cartilage CT
Filled with elastic fibers
Flexible
Maintains shape
Elastic Cartilage CT
Filled with elastic fibers
Flexible
Maintains shape
Fasciae
Connective tissue
Anchors skin to muscles and underlying organs
Deeper Fasciae - continues with other structures
Bone (Osseous Tissue) Description
Hard calcified matrix made up of collagen fibers;All cartilage is Avascular (no blood vessels)
Bone (Osseous Tissue Function
support and protection; levers for muscles to act on; stores calcium ,minerals and fat
Cartilage cells are called
Chondrocytes - also found in Lacunae
Hyaline Cartilage CT function
Connects or holds bones together
We have the most of this
Hyaline Cartilage CT
Location of Hyaline Cartilage CT
Found in between bones or on the ends (articular)
Examples of Hyaline Cartilage CT
ribs attached to sternum
Fibrocartilage CT description
Matrix with thick collagen fibers
Fibrocartilage CT function
Tensile strength with ability to absorb compressive shock
Location of Fibrocartilage CT function
Located between vertebrae (intervertebral discs) and meniscus
Description of Blood CT
Red and white blood cells in a fluid matrix(plasma)
Function of Blood CT
Transport of respiratory gases, wastes and other substances
Location of BLood CT
contained within blood vessels
Nervous Tissue Description
nuerons that are branching cells
Nervous Tissue Function
Neurons transmit electrical signals from sensory receptors to and to effectors (muscles&glands) to control their activity
Used for communication
Location of Nervous Tissue
Brain Spinal cord and nerves
Skeletal muscle Description
Tightly packed together with striations (striped appearance)
Function of Skeletal muscle
Voluntary Body Movement
Location of Skeletal Muscle
Attached to bones occasionally skin
Description Cardiac Muscle
Cells are shorter and branch and are striated
Function of Cardiac Muscle
Pumps blood Involuntary
Location of cardiac muscle
heart
Smooth muscle tissue description
Smooth - no striations
Not wavy
Smooth muscle tissue function
Moves food &fluid thru body
Involuntary
Smooth muscle tissue location
Walls of hollow organs
