Presentation Transcript

1 in which plane does inversion and eversion of the ankle joint take place
1) IN WHICH PLANE DOES INVERSION AND EVERSION OF THE ANKLE JOINT TAKE PLACE?

  • Frontal or coronal plane


2 name the ligaments that would be injured in an inversion injury of the ankle
2) JOINT TAKE PLACE?NAME THE LIGAMENTS THAT WOULD BE INJURED IN AN INVERSION INJURY OF THE ANKLE

  • When an ankle is injured from twisting in towards the other foot, called an inversion injury, most commonly the Anterior Talofibular ligament is stretched.

  • Calcaneofibular (CFL) is the second most common ligament injured after the anterior talofibular ligament (ATFL).


3 the articulation of which bones form the ankle joint
3) THE ARTICULATION OF JOINT TAKE PLACE?WHICH BONES FORM THE ANKLE JOINT?

  • The Ankle joint is made up of the Talus, the distal Tibia, and the distal Fibula

  • The articulation between the Tibia and the Talus bears more weight.


4 enumerate the movements possible in the ankle joint
4) ENUMERATE THE MOVEMENTS POSSIBLE IN THE ANKLE JOINT. JOINT TAKE PLACE?

  • DORSIFLEXION (Flexion): dorsal flexion; movement of the top of the ankle and foot toward the anterior tibia bone.

  • PLANTAR FLEXION (extension): movement of the ankle and foot away from the tibia.

  • EVERSION: turning the ankle and foot outward; abduction, away from the midline; weight is on the medial edge of the foot.

  • INVERSION: turning the ankle and foot inward; adduction, toward the midline; weight is on the lateral edge of the foot

  • TOE FLEXION: movement of the toes toward the plantar surface of the foot

  • TOE EXTENSION: movement of the toes away from the plantar surface of the foot.

  • PRONATION: a combination of ankle dorsiflexion, subtalar eversion, and forefoot abduction (toe-out)




6 what is the distal medial end of tibia called
6) WHAT IS THE DISTAL MEDIAL END OF TIBIA CALLED? ANKLE JOINT

  • The predominant structure at the distal end of the tibia is the medial malleolus


7 where does the tibia connect to the fibula medially
7) WHERE DOES THE TIBIA CONNECT TO THE FIBULA MEDIALLY? ANKLE JOINT

  • The fibula is placed on the lateral side of the tibia, with which it is connected superiorly and inferiorly by the Superior tibiofibular joint and the Inferior tibiofibular joint.


8 what is the function of gastrocnemius muscle
8) WHAT IS THE FUNCTION OF GASTROCNEMIUS MUSCLE? ANKLE JOINT

  • The function of the gastrocnemius muscle is ankle plantar flexion and knee flexion


9 where is the insertion of the tibialis posterior muscle
9) ANKLE JOINTWHERE IS THE INSERTION OF THE TIBIALIS POSTERIOR MUSCLE?

  • The tibialis posterior has multiple insertions on the lower inner surfaces of the navicular, cuneiform, and second through fifth metatarsal bases.


10 where can you palpate the tibialis anterior muscle
10) Where can you palpate the ANKLE JOINTtibialis anterior muscle?

  • It is the first muscle to the lateral side of the anterior tibial border


11 which nerve supplies the gastronemius muscle
11) Which nerve ANKLE JOINTsupplies the gastronemius muscle?

  • Tibial nerve: S1, S2


12 the eversion of the ankle joint is governed by which muscles
12) The eversion of the ankle joint is governed by which muscles?

  • peroneus longus, peroneus brevis


What is the function of flexor digiti minimi
What is the function of flexor digiti minimi? muscles?

  • Abduction of the proximal phalanx of the fifth phalange


14 locate the following parts of the ankle and foot on a subject
14) muscles?Locate the following parts of the ankle and foot on a subject

  • a- Lateral malleolusb- Medial malleolusc- Phalangesd- Metatarsal bone


15 demonstrate the following movements
15) muscles?Demonstrate the following movements.

  • a- Plantar flexionb- Dorsal flexionc- Inversiond- Eversione- Flexion of toes


16 list the plane in which the following movement takes place
16) List the plane in muscles?which the following movement takes place.

  • a- Plantar flexionb- Flexion of toe Both take place in the sagittal plane.


If a person injures his lateral planter nerve then which movement is likely to get affected
If a muscles?person injures his lateral planter nerve then which movement is likely to get affected?

  • Flexion of the 3rd, 4th, 5th phalanges


18 where is the insertion of the adductor hallucis muscle and what is its function
18) muscles?Where is the insertion of the Adductor hallucis muscle, and what is its function?

  • Insertion is on the lateral aspect on the base of the 1st proximal phalanx.

  • Function is adduction of the great toe and assists the flexor hallucis brevis in flexing the great toes at the metatarsophalangeal joint.


19 which movement helps a person to walk in terrain plain
19) Which movement helps a person to walk in terrain plain? muscles?

  • Per Dr. Ray’s instructions, omit this question.


20 what are the functions of the flexor hallucis longus muscle
20) What are the functions of the flexor hallucis longus muscle?

  • Flexion of the great toe at the metatarsophalangeal joint (MTP) and interphalangeal joint

  • Inversion of the foot

  • Plantar flexion of the ankle


21 name the nerve supplying the following muscles
21) Name the nerve supplying the following muscles muscle?

  • a.Extensor Digitorum Longus deep peroneal nerve

  • b. Peroneus brevis superficial peroneal nerve

  • c. Soleus tibial nerve

  • d. Lumbricals medial and lateral plantar nerves

  • e. Plantar interossei lateral plantar nerve


22 how can you strengthen your gastrocnemius
22) muscle?How can you strengthen your gastrocnemius?

  • Running, jumping, hopping, and skipping exercises.

  • Heel-raising exercises with the knees in full extension and the toes on a raised surface.


23) During the concentric contraction of the soleus and gastrocnemius, what type of contraction will take place in the tibialis anterior?

  • Concentric contraction is defined as a contraction in which there is shortening of the muscle the causes motion to occur.

  • Because the tibialis anterior is on the opposite side of the lower leg from the soleus and gastrocnemius it will be performing the opposite action, So if the gastrocnemius and the soleus are concentrically contracted the tibialis anterior will be eccentrically contracted.


24 what is the action of the peroneous brevis
24) What is the action of the peroneous brevis? gastrocnemius, what type of contraction will take place in the tibialis anterior?

  • Plantar flexion of the ankle

  • Eversion of the foot


25 complete the table
25) Complete the table gastrocnemius, what type of contraction will take place in the tibialis anterior?
