### body part | tissue | cartilage:

Articular cartilage
* can repair itself, to a certain degree, after injury.
* contains more collagen than other types of hyaline cartilage.
* covers the end of the femur, the top of the tibia, and the back of the patella
  - ends of the bones that make up any joint
* firm rubbery protein material covering the end of a bone.
* has no blood supply
  - several features that affect the fate of apoptotic bodies
* highly hydrated material.
* is composed primarily of elastic cartilage
  - specialized tissue that covers the ends of the bones
* is the cartilage that covers the bone and the joint areas
  - flexible connecting tissue in a joint
  - smooth cartilage that covers the bone in the knee and other joints
* plays an important role in optimal joint function.
* thin yet durable tissue that covers the ends of the thigh and shin bones.
* wears out early, causing precocious arthritis of the spine and big joints.

Epiphyseal cartilage
* closes off signaling the end of skeletal growth.
* is normal and calcifies in the normal way.

### body part | tissue | cartilage:

Fibrocartilage
* are cartilages.
* has a limited distribution
  - characteristics similar to both dense connective tissue and hyaline cartilage
  - limited ability to withstand shock and shearing forces
  - only very limited distribution in the body
* is found in the intervertebral disks and the meniscus of the knee joint
  - disks, and is an extremely resilient tissue
  - present at the insertion of ligaments and tendons into bone
* provides good resistance to shear and compression forces.
* softens the pressure that is exerted from the bones.
* very tough form that is found in the disks of the spinal column.

Fibrous cartilage
* has the least amount of cells so it has the most amount of intercellular space.
* is found in the spine and the menisci.

Healthy cartilage
* absorbs the shock of movement.
* allows bones to glide over one another.
* increases mobility and flexibility.

Hyaline cartilage
* consists of chondrocytes and extracellular matrix
  - mostly Type II collagen
* contains no blood vessels or nerves.
* forms the growth plates.
* has less cells than elastic cartilage, there is more intercellular space.
* is also what makes up the cartilage in the nose, bronchi, larynx and trachea
  - composed of four distinct histologic zones
* is found in several places
  - the nose and tracheal rings
  - is the cricoid, thyroid, and arytenoid cartilages
  - normal type

Chlorotic tissue
* becomes necrotic progressing inwards.
* common symptom of virus infection.

Collagenous tissue
* exists virtually everywhere in the organism.
* includes tendons, ligaments, scar and joint capsules.

Cornea
* Some corneas are more susceptible to corneal abrasion.
* Some corneas are part of eyes
  - faces
  - lead to blindness
* are body parts
  - epitheliums
  - membranes
* are part of eyeballs
  - solid objects
* can give sight, bones can give mobility, skin can give renewed hope to a burn victim.
* clouding from pressure is one source of visual blurring.
* have purposes.
* includes corpi.
* is animal tissue

### body part | tissue | cornea:

Corneal transplantation
* common treatment that is safe and successful.
* is the most frequently performed transplant procedure
  - second-most common transplant procedure
* wonder of modern ophthalmology.

Corneal tissue
* has the same refractive index as water.
* is removed simply by exposing tissue to the ultraviolet light.
* needs oxygen to remain healthy.

Damaged tissue
* can be the result of a heart attack, or a severe illness such as rheumatic fever.
* can, with proper exercise and a nutritional diet, be effectively and safely rebuilt.
* releases histamine that attracts white blood cells.

Dense connective tissue
* contains blood vessels.
* contains large blood vessels

Dense tissue
* Most dense tissue contains blood vessels
  - collagen fiber
* Most dense tissue contains large blood vessels
