Originally Answered: Why is Sartorius known as the honeymoon muscle? It is called so because it causes abduction and lateral rotation at hip joint which would be a critical action for all the action that is required during the Honeymoon. It causes opening of thigh and flexibility of thighs.
What is the function of the rectus femoris?
Thus the rectus femoris received its name because it runs straight down the thigh. It is a two way acting muscle as it crosses over the hip and knee joint, therefore, it functions to extend the knee and also assists iliopsoas in hip flexion.
Which muscle is synergistic with the gracilis?
The hip adductor synergy consists of adductor magnus, adductor longus and gracilis (superficial), adductor brevis and pectineus (intermediate), quadratus femoris, and obturator externus (deep).

How long is the gracilis muscle?
The gracilis is a long, thin, straplike muscle lying on the medial aspect of the thigh that measures approximately 25 cm in length and 6 cm proximally to 4 cm distally in width.
What is the function of adductor magnus?
The adductor magnus can be likened to the deltoid muscle, one portion flexes the thigh and works as a medial rotator while the other extends the thigh and is a lateral rotator, and both portions adduct the thigh.
What is the function of the adductor muscles in a clam?
The muscles are strong enough to close the valves of the shell when they contract, and they are what enable the animal to close its valves tightly when necessary, such as when the bivalve is exposed to the air by low water levels, or when it is attacked by a predator.
What is the function of the adductor brevis?
As its name suggests, the main function of the adductor brevis muscle is adduction of the thigh. This action is particularly active when the thigh is in a flexed position and during the gait cycle. Adductor brevis also has a role in external rotation and flexion of the hip.
Which is the longest muscle?
The sartorius muscle is the longest muscle in the human body. It is strap-like, up to 600 mm in length, and contains five to seven neurovascular compartments, each with a neuromuscular endplate zone. Some of its fibers terminate intrafascicularly, whereas others may run the full length of the muscle.
What is the smallest muscle in the body?
Stapedius muscle is termed to be the smallest skeletal muscle in human body, which has a major role in otology. Stapedius muscle is one of the intratympanic muscles for the regulation of sound.
Where is the longest muscle in the human body located?
The longest muscle in your body is the sartorius, a long thin muscle that runs down the length of the upper thigh, crossing the leg down to the inside of the knee. The primary functions of the sartorious are knee flexion and hip flexion and adduction.
What are the 3 hamstring muscles?
There are three hamstring muscles:
- Semitendinosus.
- Semimembranosus.
- Biceps femoris.
What are the 4 hamstring muscles?
The semitendinosus, semimembranosus, and biceps femoris muscles comprise the hamstring muscle group.
What are the 4 muscles of the quadriceps?
It has four parts: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.
What causes gracilis pain?
An injury to your low back may cause irritation of the nerve that supplies information to your gracilis. Herniated discs, disc degeneration, or lumbar facet arthritis can pinch on nerves, leading to pain or weakness in your gracilis.
What are the antagonists at the hip?
Table 2
| Muscle | Action | Antagonist |
|---|---|---|
| Gluteus maximus | Hip extension | Psoas, Rectus Femoris |
| Gluteus medius | Hip abduction | Psoas, Adductors |
Can a tight gracilis cause knee pain?
Another rare PA pathology is ‘snapping PA syndrome,’ which causes medial knee snapping. This snapping sensation results from a translation of the PA tendons (usually gracilis or semitendinosus) across the posteromedial aspect of the medial femoral condyle and tibia during knee movement(14,15).
