Where is the tibialis anterior muscle located?
Upper arm

Correct Answer : B
The tibialis anterior muscle is located in the lower leg, on the lateral side of the tibia.
It originates from the lateral condyle and surface of the tibia and the interosseous membrane, and inserts into the medial cuneiform and first metatarsal bones of the foot. It acts to dorsiflex and invert the foot.
Choice A is wrong because the upper arm does not contain the tibialis anterior muscle.
The upper arm contains muscles such as biceps brachii, triceps brachii, and brachialis.
Choice C is wrong because the thigh does not contain the tibialis anterior muscle.
The thigh contains muscles such as quadriceps femoris, hamstrings, and adductors.
Choice D is wrong because the abdomen does not contain the tibialis anterior muscle.
The abdomen contains muscles such as rectus abdominis, obliques, and transversus abdominis.

Vastus lateralis. This is because the vastus lateralis is one of the four muscles that make up the quadriceps femoris group, along with the rectus femoris, vastus medialis, and vastus intermedius.
These muscles are located in the anterior and lateral sides of the thigh and are responsible for extending the knee and flexing the hip.
Choice A. Gastrocnemius is wrong because it is not part of the quadriceps femoris group, but rather a muscle of the posterior leg that plantarflexes the ankle and flexes the knee.
Choice B. Trapezius is wrong because it is not part of the quadriceps femoris group, but rather a muscle of the back and neck that elevates, depresses, retracts, and rotates the scapula.
Choice D. Rectus abdominis is wrong because it is not part of the quadriceps femoris group, but rather a muscle of the anterior abdominal wall that flexes the trunk and compresses the abdomen.

Cellular contact inhibition is important in this process because it prevents cells from migrating and proliferating excessively when the wound is closed. Contact inhibition is a cell property that limits the migration and proliferation of cells in crowded environments.
Choice A is wrong because sweat production does not involve contact inhibition. Sweat glands secrete sweat through ducts that open onto the skin surface.
Choice C is wrong because scoliosis development does not involve contact inhibition. Scoliosis is a condition that causes the spine to curve sideways, and it can be caused by genetic, environmental, or unknown factors.
Choice D is wrong because tyrosinase production does not involve contact inhibition.
Tyrosinase is an enzyme that catalyzes the production of melanin, a pigment that gives color to the skin, hair, and eyes.
