ii. Saddle is a type of synovial joint
i. The synovial joints ischaracterised by the presence of a fluid filled synovial cavity between the articulating surfaces of the two bones.
ii. Saddle is a type of synovial joint
Answer : Option A
Explaination / Solution:
Synovial joints are characterised by the presence of a fluid filled synovial cavity between the articulating surfaces of the two bones.
A saddle joint is a synovial joint where one of the bones forming the joint is shaped like a saddle with the other bone resting on it like a rider on a horse. Saddle joint (between carpal and metacarpal of thumb)
Q3. The following X-ray shows :

Explaination / Solution:
The X-ray of knee shows gout in the knee. Gout is a kind of arthritis. It can cause an attack of sudden burning pain, stiffness and swelling in joint.
Q4. The joint present between the carpals is
Answer : Option D
Explaination / Solution:
Many gliding joints are formed in the appendicular skeleton between the carpal bones of the wrist; between the carpals and the metacarpals of the palm; between the tarsal bones of the ankle; and between the tarsals and the metatarsals of the foot.

Q6. Read the following statements and view carefully the figure :
i. Osteoporosis is an age-related disorder characterised by decreased bone mass. Osteoarthritis is shown in the following figure.
ii. The above figure shows gouty arthritis which is caused by inflammation of joints.
iii. Decreased levels of estrogen is a common cause for increased chances of fractures.
iv. Inflammation of joints is caused by decreased levels of calcium ions in body fluids.
i. Osteoporosis is an age-related disorder characterised by decreased bone mass. Osteoarthritis is shown in the following figure.
ii. The above figure shows gouty arthritis which is caused by inflammation of joints.
iii. Decreased levels of estrogen is a common cause for increased chances of fractures.
iv. Inflammation of joints is caused by decreased levels of calcium ions in body fluids.
Answer : Option D
Explaination / Solution:
Osteoporosis is an age-related disorder characterised by decreased bone mass. It is mainly caused by decreased level of estrogen in blood. Osteoporosis may leads to increased chances of fracture.
Q7. In the following two graphs :
i.first graph shows: twitch summation etanus fatigue.
ii. second graph shows: incomplete and complete tetanus.
i.first graph shows: twitch summation etanus fatigue.
ii. second graph shows: incomplete and complete tetanus.
Answer : Option C
Explaination / Solution:
Graph 1 shows muscle fiber tension with time. Which occurs in order as : twitch→summation→tetanus→fatigue.
Graph 2 shows complete and incomplete tetanus. Tetanus is also known as lockjaw, which is a infection characterized by muscle spasm.
Q8. Aging will be characterised by :
Answer : Option B
Explaination / Solution:
Aging will be characterized by decreased muscle size and increased muscle fat. With aging muscle loose its contractile and elasticity nature. Fats are deposited in muscle fibres the further decrease contracting ability.
Q9.
Muscular dystrophy is a genetic disorder.
i. It is genetically inherited.
ii. Some people get affected by MD due to mutated dystrophin gene and nutritional defects at the pre-natal age.
iii. Predominantly males are affected by DMD although females can be carriers of it.
iv. Dystrophin is a protein found in tendons.
Answer : Option D
Explaination / Solution:
Muscular dystrophy is a genetic disorder and genetically inherited. It may also occurs due to mutated dystrophin gene and nutritional defects at the pre-netal age. Males are more affected by MD although females can be carriers of it.
Q10.
Read the following about joint replacement therapy :
i. Artificial joints are made from the similar material that makes our bones.
ii. Metal or plastic is used to prepare an artificial joint.
iii. Following figure shows a disfunctional joint in the knee.
iv. Above figure shows an artificial joint in the knee.
Answer : Option D
Explaination / Solution:
Artificial joints are made up of metal and plastic. The figure shown above shows artificial joint in the knee.
