Hilton's muscle is The aryepiglottic muscle. The aryepiglotticus is a muscle of the larynx running in the aryepiglottic fold from the arytenoid cartilage to the epiglottis. Answer : (a)

The knee joint is where the tibia and femur meet. Running parallel to the tibia is the fibula, the thinner and weaker bone of the lower leg. The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides The smaller bone that runs alongside the tibia (fibula) and the kneecap (patella) are the other bones that make the knee joint.So assertion and reason both are true But Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend. Is the condition for classifying joint as hinge joint Answer : (d)

Answer : (d)

As articular cartilage, hyaline is found covering the articular surfaces of bones in synovial joints. Here, hyaline cartilage reduces friction and acts as shock-absorbing tissue. Answer : (d)

The vertebral column usually consists of 33 vertebrae: 24 presacral vertebrae (7cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae). Thus 24+2( fused) = 26 Answer : (d)

Magnesium ions found in the fluid surrounding the cells generate a small electrical charge in response to the calcium ions and propels the calcium ions back across the calcium sensitive potassium pump in the cell membrane. This stimulates potassium ions to flow out of the cell, which produces muscle cell relaxation. Magnesium competes with calcium for these same binding spots to help relax your muscles. Answer : (d)

Sesamoid bones are small more or less rounded masses embedded in certain tendons and usually related to joint surfaces. Their functions probably are to modify pressure, to diminish friction, and occasionally to alter the direction of a muscle pull. Answer : (c)
