tissue Flashcards
What is connective tissue?
The most abundant and widely distributed tissue type
what are the main functions of connective tissue?
Binding and support
protection
insulation
transportation (blood)
What are the 4 classes of connective tissue?
Connective tissue proper
Cartilage
Bone
Blood
What are the 3 (dense) connective tissue proper?
Dense regular
Dense irregular
Elastic
What is the primary (mature cell type, location in the body, fibres and function of Dense regular CT?
cell type: fibroblasts
location: tendons, ligaments, respiratory tract, blood vessel walls
fibres: collagen
Function: supports, protects, and holds bones, muscles, tissues and organs in place
What is the primary (mature cell type, location in the body, fibres and function of dense irregular CT?
Cell type: fibroblasts
Location: skins lowest layer (dermis), eyeballs protective white layer coating
Fibres: collagen
Function: strength (making skin resistant to tearing by stretching from different directions
What are the 3 types of cartilage?
Hyaline cartilage
Elastic cartilage
Fibrocartilage
What is the primary (mature cell type, location in the body, fibres and function of Elastic CT?
Cell type: chondrocytes
Location: in the walls of external ear, epiglottis, cartilage in the larynx
Fibres: elastic and collagen fibres
Function: strength and resistance to stretching (form back to original position)
What are the 2 types of bone tissue?
Compact bone
Spongy bone
What is the location in the body, fibres and function of hyaline cartilage?
Location: temporary fetus (converts to bone and form temporary skeleton of fetus, epiphyseal plate, respiratory tract
Fibres: fine collagen fibres
Function: gives flexibility and support - weakest but most abundance cartilage.
What is the location in the body, fibres and function of elastic cartilage?
Location: the article of the ear, external auditoral, eustachian tube, epiglottis
Fibres: elastic
Function: supports the parts of your body that needs to bend and move to function - can bounce back to its original shape
What is the location in the body, fibres and function of fibrocartilage?
Location: the junction between the pubic bone, tendon attachments and meniscus of your knee
Fibres: collagen
Function: act as a cushion within joints
reduces stress on joints
What are the 2 types of bones?
Compact bone and Spongy bone
What is the function, location and structure of the compact bone?
Function: provides strength and protection to bones
Location: every bone in the body
Structure: closely packed osteons
What is the function, location and structure of the spongy bone?
Function: allows for bones to be lighter (easier to move around), provides balance to the compact bone
Location: in the ends of long bones, pelvic bones, ribs, skull bones and vertebrae
Structure: consists of plates (trabeculae)
