Skeletal System

Question 1

Fossa

Answer 1

depression in a bone received the articulating bone

Question 2

Notch

Answer 2

V shaped depression
Stabalises a bone

Question 3

Condyle

Answer 3

Round bump

Question 4

Processes

Answer 4

Raised area for connective tissue

Question 5

Tuberosity

Answer 5

Raised bump used for muscle attatchment

Question 6

Periosteum

Answer 6

Tough outer layer of bone for protection

Question 7

Calcium

Answer 7

Mineral essential for bone growth

Question 8

Vitamin d

Answer 8

Needed for uptake and absorption of calcium

Question 9

Collegen

Answer 9

Protein
Connective tissue of tendons

Question 10

Bone marrow

Answer 10

Soft tissue formed in bones
Red = rbc WBC and platletts
White = fat and cartilage

Question 11

Epiphyseal

Answer 11

Rounded ends of bones forms a joint 2 or more bones

Question 12

Growth plates

Answer 12

End of long bone cartilage
Site of ossifications

Question 13

Diaphysis

Answer 13

Long part of the bone
Site of growth

Question 14

Cancelleous bone

Answer 14

Sponges home
Red bone marrow
End of bone

Question 15

Compact bone

Answer 15

Hardest part of the bone
Protection

Question 16

Articulating cartilage

Answer 16

Cartilage that allow bones to move with minimum friction

Question 17

Sagital

Answer 17

Splits body left vs right
Felxion and extension occur
E.g biceps curl

Question 18

Frontal

Answer 18

Front vs back of body
Sideways movements - abduction and addiction
E.g cartwheel

Question 19

Transverse

Answer 19

Splits top vs bottom
rotational movements
E.g pirouette

Question 20

function of skeletal system

Answer 20

Red and white blood cell production
Protection of vital organs
Mineral storage
Framework support and structure
Movement and leverage
Muscle attatchment

Question 21

Vertabrae column

Answer 21

Cervicle 7
Thoratic 12
Lumbar 5
Sacrum 5
Coccyx 4

Question 22

Type of bones and example

Answer 22

Seasmoid patella
Long femur
Short tarsals
Irregular vertabrae
Flat sternum cranium scapula

Question 23

Ligaments

Answer 23

Held together by tough fibrous tissue
Stop unwanted movements hyper extension and flexing
Connect bone to bone
Stabilises a joint

Question 24

Function of each type of bone

Answer 24

Short weight bearing
Long leverages and movement and blood cell production
Irregular and flat protection of vital organs and muscle attatchment
Seasmoid reduces friction

Question 25

Joint capsule

Answer 25

Though fibrous tissue surrounding the joint Adds strengths and supports the synovial membrane

Question 26

Bursa

Answer 26

Fluid filled sac Cushioning Between tendons Decreases friction between the bones

Question 27

Synovial membrane

Answer 27

Thin with lots of epithelial cells Produces synovial fluid Lubricates a joint and decrease friction

Question 28

Fibrous cartilage

Answer 28

Softer E.g menisci in knee Add support and cushioning

Question 29

Hyaline cartilage

Answer 29

Smooth tough and shiny Found in joints at the end of a bone Lubrication and absorbs synovial fluid

Question 30

Ligaments

Answer 30

White Poor blood supply Tough fibrous tissue Stop u wanted movements Stabalises a joint Joins bone to bone

Question 31

Blood viscosity

Answer 31

High temperature e.g exercising Viscosity of blood is thin Low temperature e.g no exercise Bloody viscosity is thick

Question 32

All type of joint and example

Answer 32

Saddle thumb Ball and socket shoulder and hip Hinge elbow ankle knee Pivot neck Condyloid wrist Gliding ankle acts like hinge

Question 33

Classifications of joins all points and examples

Answer 33

Fibrous Protection of vital organs e.g cranium No movement Held by fibrous tissue interlocking and overlapping of bones Cartilaginous Shock absorbent and cushioning Vertabrae column little movement E.g when jumping and landing protection Synovial E.g knee Freely moveable Movement production correct technique Synovial fluid lubricates and reduce friction Bursa fluid filled sac reduce friction

Question 34

Bone remodelling

Answer 34

Osteoblasts Ossifications Osteocytes Osteoclasts Calcium Vitamin D Collegen

Question 35

Osteoclasts

Answer 35

Break down and remove old damaged calcium

Question 36

Osteoblasts

Answer 36

Transport new calcium to site of bone growth Layer of Collegen is formed connective tissue in tendons
