Module 5: Cartilage and Bone (Anatomy
337 UW Madison) Exam |91 Accurate Q’s
and A’s
What two major forms of supportive connective tissue allow the body to
maintain its posture and protect internal organs? - -Cartilage and bone!
- What cells are embedded within the cartilage matrix? What are the spaces
that they occupy called? - -chondrocytes (cartilage cells- mature part of the
cell), chondroblasts-builder of tissue. lacunae
- What is the perichondrium? What does it encapsulate? - -A layer of dense
irregular connective tissue, encapsulates the cartilage, it resists outside
pressure. The stem cells will become chondroblasts
- Is cartilaginous tissue avascular or vascular? - -Cartilaginous tissue is
avascular
- What are the three main types of cartilage tissue? - -The three main types
of cartilage tissue are hyaline cartilage, fibrocartilage, and elastic cartilage.
- Most common type, Hyaline cartilage
-Made of what?
- Characteristics?
-Functions?
-Examples? - --consists of short and dispersed collagen fibers.
-The surface of hyaline cartilage is smooth. Both strong and flexible
- Provides stiff but somewhat flexible support, reduces friction between bony
surfaces
-found in the rib cage and nose and covers bones where they meet to form
moveable joints
- What does a plate of hyaline cartilage at the ends of bone (growth plate)
allow? - -It allows continued growth until adulthood
- Fibrocartilage
-Made of what?
- Characteristics?
-Functions?
-Examples? - -- thick bundles of collagen fibers dispersed through its matrix
-Tough
- Resists compression; prevents bone-to-bone contact, limits relative
movement
, -Menisci in the knee joint and the intervertebral discs are examples of
fibrocartilage
- Elastic cartilage
-Made of what?
- Characteristics?
-Function?
-Examples? - -- Contains elastic fibers as well as collagen
-Tissue gives rigid support and elasticity
- Provides support, but tolerates distortion without damage and returns to
original shape
-Ear lobe (when you tug it, it goes back)
- Bone is the ___________ connective tissue. It protects _________ _________
and supports _______ _______. - -hardest, internal organs, the body
- Osteocytes (bone cells) like chondrocytes are located........ - -within
lacunae.
- Is bone vascularized? How is bone different than cartilage? - -Yes, it is a
highly vascularized tissue. Unlike cartilage, bone tissue can recover from
injuries in a relatively short time.
- What does spongy (cancellous) bone look like?
Is it heavier or lighter than compact bone? Where is it found?
What does compact bone look like? - -Spongy (cancellous) bone contains
empty spaces between trabeculae. It is lighter than compact bone and is
found in the interior of some bones and at the end of long bones. Compact
bone is solid and has greater structural strength.
No central canal, does NOT contain osteons. Trabeculae lays in a place for
the stresses, makes body strong in multiple directions. Reduces weight of
bone, because more space
- True or False. Bone, or osseous tissue, is a hard, dense connective tissue
that forms most of the adult skeleton, the body's support structure. - -True
- The skeletal system is the body system composed of _________ and ________
and performs the following critical functions for the human body?
-
-
-
-
-
- - -bones and cartilage
