Anatomy Anterior And Lateral Leg 10/6

Front 1

What is the main action of the anterior leg muscles, lateral? dorsiflexion= what in upper extremities?

Back 1

anterior- dorsiflex the foot
lateral- evert the food

extension

Front 2

Which anterior thigh muscles are indicated in shin splints?

Back 2

tibialis anterior, small tears over periosteum over tibia and tears to overlying deep fascia

Front 3

What are the four anterior compartment muscles?
What is common action of all them and individualized?

Back 3

1. extensor digitorum longus- extends digits 2-5
2. extensor hallucis longus- extends first digit
3. fibularis tertius- everts food
4. tibialis anterior
all are innervated from deep fibular nerve (L4-S1) except tertius is L5-S1
all involed with dorsi flexion

Front 4

What are the two lateral compartment muscles? What are innervations and individual actions?

Back 4

1. fibularis longus-
2. fibularis brevis
both are innervated from superficial fibular nerve (L5-S2)
Both evert foot and have weak plantar flexion

Front 5

What is crural (leg) fascia and its role?

Back 5

deep fascia of leg that is continuous with fascia lata and covers leg muscles
- distally it forms extensor retinaculum

Front 6

If an athlete exerts himself too much and swells his muscles what might happen?
What surgical technique can be done to relieve pressure from compartmental syndromes?

Back 6

swollen muscles could compress arteries and not allows blood flow to certain compartments of legs

- fasciotomy- incising fascia

Front 7

A dude was hit in the thigh by a hammer... which artery is likely to compress and cause ischemia?

Back 7

popliteal

Front 8

From a blow to the knee I fracture the head and neck of the fibula... what condition might occur and why from this condition?

Back 8

anterior tibial compartment syndrome due to ischemic necrosis of anterior muscles

Front 9

Which muscle is affected by the following examples...
a. man comes in and has problem dorsi flexing

Back 9

a. all anterior compartment muscles

Front 10

What nerve supplies:
1. anterior compartment muscles
2. ankle joint and metacarpal phalangeal joints
3. dorsal intrinsic foot muscles
4. skin between first and second digits

Back 10

deep fibular nerve

Front 11

What artery brings blood anterior compartment of leg? Where does it come from/go?

Back 11

anterior tibial artery from popliteal artery becomes dorsalis pedis artery

Front 12

What nerve goes to anteroinferior leg, most dorsal surface of foot, and most dorsal aspect of toes?

Back 12

superificial fibular nerve (L5-S2)
