Muscle Tussle Trivia Quiz

Answer: Trapezius

The three muscles of the posterior thigh are called collectively the hamstring muscles. Their purpose is to aid in bending and flexing the knee and extending and straightening the hip. Squats, leg curls, and dead lifts are often exercises used to strengthen the hamstring muscles. The trapezius is in the shoulder.

Answer: Gluteus maximus

There are four main muscles in the quadriceps group including the rectus femoris, the vastus medialis, the vastus intermedius, and the vastus lateralis. The quadriceps muscles perform an antagonist function to the hamstring muscles. These four muscles are powerful extensors of the knee joint and also play a role in stabilizing the knee cap. Strength training exercises that promote quad strength include the leg press and squats.

Answer: Articularis genus

The articularis genus is a small skeletal muscle located on the anterior of the thigh just above the knee. During extension of the knee this muscle prevents impingement of the synovial membrane between the long leg bone femur and the patella.

Answer: Auriculares

Th auriculares muscles include the auricularis anterior, which can pull the ear up and forwards, the auricularis superior that raises the ears, and the auricularis posterior which has the capacity to pull the ear backwards. Ear wiggling is a vestigial trait which means it once played an important purpose but, through evolution, has become functionless in humans. Research suggests that somewhere between 10% and 20% of the population can wiggle their ears.

Answer: Risorius

The risorius muscle is thought to only be found in humans and great apes. The muscle is found in the face and it retracts the angle of the mouth in order to produce a smile. Unlike a real smile that engages other facial muscles such as the zygomaticus minor and zygomaticus major, the risorius produces a mirthless smile.

Answer: Flexor hallucis longus

The flexor hallucis longus is one of three deep muscles comprising the posterior compartment of the leg that connects to the hallus (big toe). The other two muscles that make up this compartment include flexor digitorum longus and the tibialis posterior.

The tibial nerve provides innervation for all three of these muscles. The flexor halluces longus plays a role in flexion of the big toe and the supination of the ankle.

Answer: Genioglossus

Biceps, triceps, and deltoids are all muscles of the upper body and play an important role in coordinating power movements in many sports. The genioglossus is actually one of eight muscles of the human tongue. Four of those muscles are considered extrinsic and act to aid in changing the position of the tongue (genioglossus, hyoglossus, styloglossus, and palatoglossus).

The remaining four muscles are considered intrinsic and help shape the tongue as well as aid in eating, swallowing, and speech (superior longitudinal muscle, inferior longitudinal muscle, vertical muscle and transverse muscle).

Answer: 9

Amazingly, nine different muscles contribute to the movement of the little finger. Two work as extrinsic flexors (flexor digitorum superficialis and flexor digitorum profundus). Two muscles act in an extensor function (extensor digiti minimi and extensor digitorum). Two muscles are intrinsic hand muscles (fourth lumbrical muscle and third palmar interosseous muscle). Finally, there are three muscles in the hypothenar eminence including the opponens digiti minimi, abductor minimi digiti and the flexor digiti minimi brevis.

The term pinky in reference to the little finger is actually from the Dutch word pink meaning literally "little finger".

Answer: Pubococcygeus muscle

The pubococcygeus or PC muscle is a hammock-shaped muscle found in both males and females. It stretches from the tail bone to the pubic bone and is an important supporting role to the pelvic organs. Aside from serving functions related to urination and orgasm, the pubococcygeus muscle also aids in childbirth. An important exercise to improve this muscle's strength is Kegel exercises which are voluntary contractions of the perineal muscles.

Answer: Gluteus maximus

The gluteus maximus muscle is the true powerhouse of the human body and the largest muscle. This muscle is comprised of skeletal muscle that is influential in walking, lifting, jumping, and most all ambulatory movements. One of the very best exercises to improve strength and development of the gluteus maximus is simple lunges.

The brain of course is not now or ever has been a muscle. It does however, like muscles, atrophy when left inert and continues to grow and develop strength when exercised with quizzes like this one.
