Gastrocnemius Essay, Research Paper Gastrocnemius Origin: 1.medial caput: posterior surface of the median femoral condyle 2.lateral caput: posterior surface of the sidelong femoral condyle Interpolation: posterior surface of the heelbone ( Achilles tendon ) Action: 1.plantar flexure the mortise joint 2.knee flexure ( when non burden bearing ) Nerve: tibial nervus, S1,2Application, beef uping A ; flexibleness: # 183 ; Because the gastroc. Is a biarticular musculus, it is more effectual as a articulatio genus flexor if the mortise joint is dorsiflexed and more effectual as a plantar flexor of the foot. # 183 ; When the articulatio genuss are dead set, the musculus becomes an uneffective plantar flexor. # 183 ; Running, jumping, hopping, and jumping exercisings all depend on the gastroc and soleus to impel the organic structure upward and frontward. # 183 ; Heel raising exercisings with the articulatio genuss in full extension and the toes resting on a block of wood are an first-class manner to beef up the musculus t hrough the full scope of gesture.

Soleus Beginning: Posterior surface of the proximal calf bone and proximal 2/3 of the posterior tibial surface Interpolation: posterior surface of the calcaneus Action: plantar flexure the pes Nerve: tibial nervus, S1,2Application, beef uping A ; flexibleness: # 183 ; The soleus is stretched in the same mode as the gastroc except that the articulatio genuss must be flexed somewhat, which releases the stretch on the gastroc and topographic points it on the soleus. Again it is of import to maintain the heels on the floor. Tibialis posterior Beginning: 1.posterior surface of the upper half of the interosseus membrane and next surfaces of the shinbone and calf bone. Interpolation: 1.Lower interior surfaces of the scaphoid and cuneiform bone and bases of the 2nd, 3rd, 4th, and 5th metatarsal castanetss. Action: 1.Plantar flexure of the ankle 2.inversion of pes Nerve: tibial nervus, L5, S1Application, beef uping A ; fle xibleness: # 183 ; ? Shin Splints? is a slang term often used to depict an frequently chronic status in which the tibialis buttocks, tibialis front tooth, and extensor digitorum longus musculuss are inflamed. # 183 ; Dashs and long-distance running are common causes, peculiarly if the jock has non developed appropriate strength, flexibleness, and endurance in the lower leg musculature. # 183 ; The tibilias buttocks may be stretched by passively taking the pes into utmost eversion and dorsiflexion while the articulatio genus is flexed. Flexor digitorum longus Beginning: 1.middle 3rd posterior surface of tibia Interpolation: bases of the 2-5th distal phalanges Action: 1.primarily flexes 2nd # 8211 ; 5th toes 2. plantar flexure of ankle 3.inversion of pes Nerve: tibial nervus, L5, S1Application, beef uping A ; flexibleness: # 183 ; It may be strengthened by executing towel grabs against opposition in which the heel remainders on the floor while the toes extend to catch a level to wel and the flex to draw the towel under the pes. This may be repeated legion times, with a little weight placed on the opposite side of the towel for added opposition. # 183 ; The flexor digitorum longus may be stretched by passively taking the four lesser toes into utmost extension while the pes is everted and dorsiflexed. The articulatio genus should be flexed. Flexor hallucis longus Beginning: 1.middle 2/3 of the posterior surface of fibula Interpolation: Base of the distal phalanx of the large toe, under the surface Action: 1.flexes large toe ( big toe ) 2.plantar flexure of the ankle 3.inversion of pes Nerve: tibial nervus, L5, S1,2Application, beef uping A ; flexibleness: # 183 ; Running, walking, jumping, hopping, and skipping provide exercise for this muscle group. The flexor hallucis longus muscle may be specifically strengthened by performing towel grabs as described for the flexor digitorum longus. · The flexor hallucis longus may be stretched by passively taking the great toe into extreme extension while the foot is everted and dorsiflexed. The knee should be flexed. Peroneus longus Origin: 1.head and upper 2/3 of the lateral surface of the fibula Insertion: 1.undersurfaces of the medial cuneiform and first metatarsal bones Action: 1.eversion of the foot 2. plantar flexion of the ankle Nerve: superficial peroneal nerve, L4,5,S1Application, strengthening flexibility: · Eversion exercises to strengthen this muscle mat be performed by turning the sole of the foot outward while resistance is applied in the opposite direction. · The Peroneus longus may be stretched by passively taking the foot into extreme inversion and dorsiflexion while the knee is flexed. Peroneus brevis Origin: 1.lower 2/3 of lateral fibula Insertion: tuberosity of 5th metatarsal Action: 1.eversion of the foot 2. plantar flexion of foot Nerve: superficial peroneal nerve, L4,5,S1 Peroneus tertius Origin: 1.distal 1/3 of anterior fibula Insertion: base of 5th metatarsal Action: 1.eversion of the foot 2.dorsal flexor of the ankle Nerve: deep peroneal nerve, L4,5,S1 Tibialis anterior Origin: 1.upper 2/3 of the lateral surface of the tibia Insertion: 1.inner surface of the medial cuneiform and the 1st metatarsal Action: 1. dorsiflexor of the ankle 2.inverts the foot Nerve: deep peroneal nerve, L4,5,S1Application, strengthening flexibility: · Turning the sole of the foot inside against resistance to perform inversion exercises is one way to strengthen this muscle. Dorsal flexion exercises against resistance may also be used for this purpose.  · Tibialis anterior may be stretched by passively taking the foot into extreme eversion and plantar flexion Extenso r digitorum longus Origin: 1.lateral condyle of the tibia 2.head of the fibula 3.upper 2/3 of the anterior surface of the fibula Insertion: 1. tops of the middle distal phalanxes of the 2nd-5th toes Action: 1.extends the lateral 4 toes 2.dorsiflexor of the ankle Nerve: deep peroneal nerve, L4,5,S1Application, strengthening flexibility: · Action that involves dorsal flexion of the ankle and extension of the toes against resistance strengthens both the extensor digitorum longus and the extensor hallucis longus muscles. This may be accomplished by manually applying downward force on the toes while attempting to extend them up. · The extensor digitorum longus may be stretched by passively taking the four lesser toes into full flexion while the foot is inverted and plantar flexed. Extensor hallucis longus Origin: 1.medial 2/3 of the medial surface of the anterior fibula Insertion: base of distal phalanx of big toe Action: 1.extends distal phalanx of big toe 2.dorsiflexor of the ank le 3.weak inversion of the foot Nerve: deep peroneal nerve, L4,5,S1Application, strengthening flexibility: · The three dorsiflexors of the foot ? tibialis anterior, extensor digitorum longus, and extensor hallucis longus ? may be exercised by attempting to walk on the heels with the ankle dorsiflexed against resistance, will provide strengthening for this muscle. · The extensor hallucis longus may be stretched by passively taking the great toe into full extension while the foot is everted and plantar flexed.
