plantaris muscle การใช้
- In addition, the plantaris muscle does atrophy.
- The plantaris muscle and a portion of its tendon run between the two muscles.
- Muscular branches of the popliteal artery supply the hamstring, gastrocnemius, soleus, and plantaris muscles.
- The plantaris muscle may also provide proprioceptive feedback information to the central nervous system regarding the position of the foot.
- It originates from the femur on the inner side of the plantaris muscle and inserts into the posterior ligament of the knee-joint.
- Not including the tendon, the plantaris muscle is approximately 5 10 cm long and is absent in 8-12 % of the population.
- Isolated plantaris muscle strains are rare and ruptures normally occur in concurrence with injury to other muscles in the posterior compartment of the lower leg.
- Symptoms of a plantaris muscle rupture may include an audible popping sound in the area during physical activity, swelling, pain in the posterior side of the lower leg, and persistent soreness.
- In the popliteal fossa the nerve gives off branches to gastrocnemius, popliteus, soleus and plantaris muscles, an articular branch to the knee joint, and a cutaneous branch that will become the sural nerve.
- Some anatomists consider both to be a single muscle, the plantaris muscle and a portion of its tendon run between the two muscles, which is involved in " locking " the knee from the standing position.
- Intriguingly, refeeding induced myonectin mRNA expression to a much greater extent in soleus than in plantaris muscle fiber of both male and female mice ( data not shown ), suggesting that myonectin expression may be regulated differentially depending on muscle fiber type.
