Answer: Option A. -> Synovial fluid
:
A
Synovial fluid is a viscous fluid found in the cavities of synovial joints. With its egg white–like consistency, the principal role of synovial fluid is to reduce friction between the articular surfaces of synovial joints during movement.
Pleural fluid -Pleural fluidis thefluidthat is found between the layers of thepleura, the membranes that line the thoracic cavity and surround the lungs.
Lymphatic fluid - contains infection-fighting white blood cells, which circulates throughout the body.
Peritoneal Fluid - is a liquid made in the abdominal cavity which lubricates the surface of tissue that lines the abdominal wall and pelvic cavity.

Answer: Option A. -> First seven pairs
:
A
First 7 pairs of ribs are attached anteriorly to the sternum, next 3 attached to a cartilage called costochondral cartilage and the last 2 pairs do not have any anterior attachment and hence called floating ribs.

Answer: Option A. -> Pectoral girdle and Patella
:
A
The pectoral girdle is the skeletal framework which provides attachment for the forelimbs and the pelvic girdle will be the analogous pair as it provides the framework for the attachment of lower limbs. Patella is the knee cap.
Carpals are the bones in the wrist and tarsals are the analogous bones in the ankle.The humerus is the bone in the forearm and femur is the analogous bone in the forelimb.
Theatlas boneis the first of thevertebral column and the last bone in the column analogous to it is the coccyx.

Answer: Option C. -> Muscle fatigue
:
C
Prolonged stimulation of muscles/overwork lead to muscle fatigue leading to a decrease in the force of contraction. This may be due to depletion of calcium stores in the sarcoplasmic reticulum or also due to accumulation of lactic acid.

Answer: Option C. -> Vertebral column
:
C
Coccygeal bone or coccyx is also called as the tail bone. It is made up of 4 bones fused into one. It is the last bone of vertebral column.

Answer: Option A. -> Chondrocytes
:
A
Cartilage is made up ofspecialized cartilage cells called chondrocytes, which are suspended in an acellular matrix made up largely of a protein called collagen.Ossein is the collagen of bones.

Answer: Option D. -> All of the above 
:
D
In terms of appearance,smooth musclesare long, thin-shaped cells attached to bones in the body.Smooth musclegenerally forms the supporting tissue of blood vessels and hollow internal organs, such as the stomach, intestine, and bladder.

Answer: Option A. -> Fibro-cartilage that lies between adjacent vertebrae in the vertebral column
:
A
An intervertebral disc is a fibrocartilage present between the vertebrae. It acts as a shock absorber between each of the vertebrae in the spinal column by keeping the vertebrae separated when there is an impact from an activity. They also serve to protect the nerves that run down the middle of the spine and intervertebral discs.
