8 CONNECTIVE TISSUE TYPES
1.) Hyaline Cartilage
2.) Elastic Cartilage
3.) Fibrocartilage
4.) Dense Connective Tissue
5.) Areolar Connective Tissue
6.) Blood
7.) Adipose Tissue
8.) Reticular Connective Tissue
Most common cartilage
HYALINE CARTILAGE
Composed of abundant collagen fibers and rubbery matrix.
HYALINE CARTILAGE
EXAMPLE OF HYALINE CARTILAGE:
Entire Fetal Skeleton
Provides elasticity.
ELASTIC CARTILAGE
EXAMPLE OF ELASTIC CARTILAGE:
Supports the external ear.
Highly compressible. Forms cushion-like discs between vertebrae.
FIBROCARTILAGE
Main matrix element is collage fibers and cells are fibroblasts.
DENSE CONNECTIVE TISSUE
EXAMPLES OF DENSE CONNECTIVE TISSUE:
Tendon and Ligaments
Attach bone to muscle.
TENDON
Attach bone to bone.
LIGAMENTS
Most widely distributed connective tissue.
AREOLAR CONNECTIVE TISSUE
Soft pliable tissue. Contains all fiber types. And can soak up excess fluid.
AREOLAR CONNECTIVE TISSUE
Blood cells surrounded by fluid matrix.
BLOOD
Fibers are visible during clotting.
BLOOD
Functions as the transport vehicle for materials.
BLOOD
Matrix is an areolar tissue in which fat globules predominate.
ADIPOSE TISSUE
Many cells contain large lipid deposits.
ADIPOSE TISSUE
FUCTIONS OF ADIPOSE TISSUE
Insulates the body.
Protects some organs.
Serves as a site of fuel storage.
Delicate netweork of interwoven fibers.
RETICULAR CONNECTIVE TISSUE
Forms stroma (internal supporting network) of lympoid organs: LYMPH NODES, SPLEEN, AND BONE MARROW
RETICULAR CONNECTIVE TISSUE
Function is to produce movement.
MUSCLE TISSUE
THREE TYPES OF MUSCLE TISSUE:
Skeletal, Cardiac, and Smooth Muscle.
Can be controlled voluntarily.
Cells attach to connective tissue.
Cells are striated.
Cells have more than one nucleus.
SKELETAL MUSCLE
Found only in the heart.
Function is to pump blood (involuntarily)
Cells attached to other cardiac muscle cell at intercalated disks.
Cells are striated.
One nucleus per cell.
CARDIAC MUSCLE
Involuntary muscle.
Surrounds hollow organs.
Attached to other smooth muscle cells.
No visible striations.
One nucleus per cell.
SMOOTH MUSCLE
Neurons and nerve support cells.
NERVOUS TISSUE
Function is to send impulses to other areas of the body. Irritability and Conductivity.
NERVOUS TISSUE
Replacement of destroyed tissue by the same kind of cells.
REGENERATION
Repair by dense fibrous connective tissue (scar tissue)
FIBROSIS
DETERMINATION OF METHOD OF TISSUE REPAIR
Type of tissue damaged
Severity of the injury
TISSUES THAT REGENERATE EASILY:
Epithelial Tissue
Fibrous Connective Tissue and Bone
TISSUES THAT REGENERATE POORLY:
Skeletal Tissue
TISSUES THAT ARE REPLACED LARGELY WITH SCAR TISSUE:
Cardiac Muscle
Nervous tissue within the brain and spinal cord.
Epithelial tissue arises from:
All three primary germ layers
Nervous tissue arises from:
ECTODERM
FOUR PRIMARY TYPES OF BODY TISSUES:
Epithelium
Connective Tissue
Nervous Tissue
Muscle Tissue
Cells fit closely together.
Tissue layer always has one free surface.
The lower surface is bound by a basement membrane.
Avascular (have no blood supply)
Regenerate easily if well flourished.
EPITHELIUM TISSUE
Found in different areas: Body Coverings, Body Linings, and Galndular Tissue.
EPITHELIAL TISSUE
FUNCTIONS OF EPITHELIAL TISSUE:
Protection
Absorption
Filtration
Secretion
