Physiology Quiz 2 Flashcards
What is a fascicule?
Group of collagen fibers
What forms a tendon?
Group of fascicles
What surrounds fascicles?
Loose connective tissue
What surrounds tendons?
Dense irregular tissue
What covers tendons that allows movement?
Epitendineum
What is the synovial sheath?
Found where tendon passes through joint cavity or narrow space.
What do tenocytes and fibroblasts do for the tendon?
Helps repair tendons in a slow process because of the lack of blood vessels.
What is a tendon?
Dense connective tissue from bone to bone that deal with tensile forces.
What is missing from tendons?
Loose connective tissue or specialized fibroblasts
What are sharpey’s fibers?
Fibers that penetrate the bone from the periosteum
What are the functions of tendons?
Hold bones and stabilize joints
What is retinacula?
Straps of dense regular connective tissue
What is cartilage?
Semi-rigid connective tissue with high amount of fibers that deal in compressive forces (weight bearing).
How is the cartilage matrix made?
Secreted by chondroblasts and maintained by chondrocytes
What is the matrix made of?
Hyaluronic acid and chondroitin sulfate and no blood supply
What covers the matrix?
The perichondrium (Type I)
What are the types of cartilage?
Hyaline, elastic, fibrocartilage
What are the characteristics of hyaline cartilage?
- Body’s most prevalent
What are the characteristics of elastic cartilage?
- Intermediate elasticity
What are the characteristics of fibrocartilage?
- Least rigid
What are the three stages of cartilage growth?
- Interstitial
What is interstitial growth?
Chondrocytes in the lacunae have cell division
What is appositional growth?
Chondroblasts in inner periosteum adds new layers of matrix that continues until puberty
What is repair damage?
Resembles appositional growth
