#6 Movement types / Arthrology / Synovial joints

Question 1

What are chondrocytes?

Answer 1

Cells responsible for producing cartilage

The prefix ‘chondro-‘ can help associate these cells with cartilage.

Question 2

What type of joint does not allow movement?

Answer 2

Synchondrosis joints

These joints can be associated with ‘concrete’ due to their immobility.

Question 3

What is an example of a symphysis joint?

Answer 3

Pubic symphysis

This joint is where two pubic bones meet with fibrocartilage in between.

Question 4

What type of cartilage is found in symphysis joints?

Answer 4

Fibrocartilage

Fibrocartilage is tough and strong, providing slight mobility.

Question 5

What do synovial joints have that provides lubrication?

Answer 5

Synovial fluid

Synovial joints are the most mobile type but can be prone to dislocation.

Question 6

How does the human brain learn best?

Answer 6

Through repetition and practice

Associating new information with what you already know aids in learning.

Question 7

What is the relationship between joint stability and mobility?

Answer 7

Stability is inversely related to mobility

More stable joints are less likely to move and vice versa.

Question 8

What are the two types of movements associated with flexion and extension?

Answer 8

Bending and straightening movements

These movements are fundamental in joint motion.

Question 9

What does abduction refer to in joint movements?

Answer 9

Moving away from the midline

Mnemonic: ‘Abduct’ (take away).

Question 10

What does adduction refer to in joint movements?

Answer 10

Moving towards the midline

Mnemonic: ‘Add’ (bring back).

Question 11

What are the rotational movements of the forearm called?

Answer 11

Pronation and Supination

Mnemonic: ‘Pro basketball players pronate’ (to dribble).

Question 12

What is dorsiflexion in terms of foot movement?

Answer 12

Lifting toes upward

This movement is opposite to plantar flexion.

Question 13

What is plantar flexion in terms of foot movement?

Answer 13

Pointing toes downward

This movement is opposite to dorsiflexion.

Question 14

What are fibrous joints?

Answer 14

Joints that include sutures in the skull and syndesmosis in the lower leg

These joints allow little to no movement.

Question 15

What are cartilaginous joints composed of?

Answer 15

Hyaline cartilage or fibrocartilage

Synchondrosis joints have hyaline cartilage and allow no movement, while symphysis joints have fibrocartilage and allow slight movement.

Question 16

What are some effective learning tips for studying joint types and movements?

Answer 16

Use mnemonics and associations

Revisit and review material regularly to reinforce learning and engage in active learning by performing movements.
