Functional Anatomy of the Skeletal System

Question 1

What effect do weight bearing asana have on the bones?

Answer 1

When stress is placed on the bones, the Osteoblasts pull Calcium from the blood and deposit it into the bones, reforming and rebuilding the bones. Osteoclasts work to break down the bone, providing the Calcium back to the blood stream, Osteoclasts work at a higher rate than Osteoblasts and thus it is important to ‘fight’ it with weight bearing.

Question 2

What is Synovial fluid?

Answer 2

Fluid in Synovial joints, which lubricates and nourishes the joints, helps to remove waste products, works as a shock absorber for the joint, transports oxygen throughout the joint.

Question 3

What are the types of Synovial Joints? Hint: There are 6.

Answer 3

1. Ball and Socket Joint 2. Condyloid Joint 3. Gliding Joint 4. Hinge Joint 5. Pivot Joint 6. Saddle Joint

Question 4

Which type of asanas help increase bone health?

Answer 4

Standing, balancing, vinyasa, and back bends.

Question 5

What are the major functions of the Skeletal System?

Answer 5

Support, movement, and protection.

Question 6

Name the components of the Musculoskeletal System. Hint: there are 5.

Answer 6

Bones, muscles, joints, ligaments, and tendons.

Question 7

What connects the Musculoskeletal System?

Answer 7

Joints, Ligaments, and Tendons.

Question 8

Define a Joint.

Answer 8

Point of connection between two bones or elements of the skeleton.

Question 9

What is a Ligament?

Answer 9

Tough fibrous band which connects bone to bone or cartilage. They can come back to original shape once tension is removed. Nearly no blood.

Question 10

What is a Tendon?

Answer 10

Connective tissue which connects muscle to bone. Little blood and do not have much stretch.

Question 11

Name the types of joints? Hint: there are 3.

Answer 11

1. Fibrous joint 2. Cartilaginous joint 3. Synovial joint

Question 12

Define a Fibrous joint and name one example.

Answer 12

An immovable or fixed joint. Example is the skull.

Question 13

Define a Cartilaginous joint and name one example.

Answer 13

A slightly movable joint. Example is between the bones of the ribcage.

Question 14

Define a Synovial joint and name one example.

Answer 14

A freely movable joint. Example is shoulder.

Question 15

What factors affect bone health? Hint: there are 11.

Answer 15

Arthritis, degenerative disorders, osteomyelitis, bone spurs, bone cancer/tumor, cancer treatments, rheumatoid arthritis, viral diseases, lifestyle factors, osteogenesis, and achondroplasia.

Question 16

Name the 3 types of connective tissue.

Answer 16

Cartilage, ligaments, and tendons.

Question 17

Name the 3 types of fibrous tissue.

Answer 17

Collagenous fibres, elastic fibres, and reticular fibres.

Question 18

Name the 6 types of bone shapes.

Answer 18

1. Long bones (shin bone) 2. Short bones (wrist) 3. Flat bones (sternum) 4. Irregular bones (vertebrae) 5. Sesamoid bones (patella) 6. Sutural bones (within skull)

Question 19

What is joint hypermobility?

Answer 19

A joint that stretches further than considered normal, which consists of more elastic ligaments.

Question 20

The Skeleton is divided into two parts, what are they and what are they made up of (general not each individual bone)?

Answer 20

The Axial Skeleton which is the head and spine, and the Appendicular Skeleton, which is the shoulder and pelvic girdles and limbs.

Question 21

Name a pivot joint.

Answer 21

Between C1 and C2.

Question 22

Name a ball and socket joint.

Answer 22

Shoulder and hips.

Question 23

Name a condyloid joint.

Answer 23

Wrist joint.

Question 24

Name a saddle joint.

Answer 24

Thumb joint.

Question 25

Name a gliding joint (sometimes known as plane joint).

Answer 25

Carpals of the wrist.

Question 26

Name a hinge joint.

Answer 26

Elbow joint.
