DPT 6160 EXAM 1: SKELETAL SYSTEM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS
skeletal system
the internal framework of the human body composed of bones and cartilages
axial skeleton and appendicular skeleton
What are the main parts of the skeletal system?
axial skeleton
bones of the head, neck, and trunk
appendicular skeleton
bones of the pectoral girdle, upper limbs, pelvic girdle, and lower limbs
cartilage
a resilient, semi-rigid avascular type of connective tissue that forms part of the skeleton
where more flexibility is necessary
hyaline cartilage and fibrocartilage
What are the 2 types of cartilage?
hyaline cartilage
consists of chondrocytes and limited type II collagen fibers; resiliency and smooth, low-
friction surface provides cushioning for skeletal joints and sliding regions within joints to
facilitate movements
hyaline cartilage
,- articular surfaces of bones with synovial joints
- costal cartilage
- epiphyseal plates
Where can hyaline cartilage be found?
- it's avascular
- obtain nutrients by diffusion
- nutrition contained within synovial fluid
How does hyaline cartilage get its nutrients?
fibrocartilage
combination of hyaline cartilage and dense regular connective tissue; consists of
chondrocytes and ground substance found also in hyaline cartilage, but also fibroblasts
fibrocartilage
yes, from the outer rim of some fibrocartilaginous structures where they attach to
joint capsules or ligaments
Is there any blood supply in fibrocartilage tissues?
- meniscus
- intervertebral disc
- labrum of hip joint
- glenohumeral joint
- pubic symphysis
Where can fibrocartilage be found?
connective tissue proper:
- dense regular connective tissue
, specialized connective tissues:
- cartilage
- bone
- adipose tissue
What are skeletal structures made of?
1. blood vessels
2. extracellular matrix
- ground substance
- protein fibers
3. resident cells
What are connective tissues made up of?
1. elastic fibers
2. collagen fibers
3. reticular fibers
What are the different types of protein fibers?
1. binding together
2. compartmentalization
3. support
4. storage
5. protection
What are the functions of connective tissue
connective tissue proper
