Flashcards in Exam 4 Part 4 Random info Deck (24):
1

Term used to designate the deep & superficial fascia of the leg

Crural fascia

2

Binds the tendons of the anterior leg muscles & prevent the tendons from bowstringing when the foot is dorsal flexed

Superior & inferior extensor retinacula

3

Binds down the tendons of the lateral leg muscle

Fibular retinacula

4

Binds down the tendons of the deep posterior leg muscles

Flexor retinaculum

5

- Thin, but strong ligament which connects the interosseous borders of the tibia & fibula
- Large opening is found in the upper portion of the membrane to permit the anterior tibial artery to enter the anterior compartment of the leg

Interosseous membrane

6

Functions of the interosseous membrane

1. Serves as an attachment for muscles
2. Stabilizes the tibia & fibula

7

Arches of the foot

Medial longitudinal
Lateral longitudinal
Transverse

8

- Smallest of the 2 terminal branches of the sciatic nerve
- Contains fibers from L4, L5, S1 & S2
- Nerve desends to the proximal part of the fibula where it winds around the neck

Common Fibular Nerve

9

Common Fibular Nerve splits into:

Superficial & deep fibular nerve

10

Branches of the common fibular nerve (3)

1. Sural communicating
2. Lateral sural cutaneous
3. Articular

11

Joins the sural branch of the tibial nerve & helps to supply skin on the posterior aspect of the leg

Sural communicating

12

Supplies skin on the proximal lateral posterior aspect of the leg

Lateral sural cutaneous

13

Supply to the knee joint

Articular

14

- Found in the anterior compartment of the leg & is the medial terminal branch of the common fibular nerve
- Contains fibers from L4, L5 & S1
- Arises @ the neck of the fibula & descends w/ the anterior tibial artery into the anterior compartment of the leg
-

Deep fibular Nerve

15

Branches of the deep fibular nerve (3)

1. Muscular
2. Articular
3. Cutaneous

16

To the muscles of the anterior compartment of the leg & the dorsum of the foot

Muscular Branch of the deep fibular nerve

17

To the inferior tibiofibular & ankle joints

Articular branch of the deep fibular nerve

18

To a small area of skin at the webspace between the first & second digits

Cutaneous branch of the deep fibular nerve

19

- Supplies structures of the anterior compartment of the leg
- Smaller terminal branch of the popliteal artery
- passes through an opening in the proximal portion of the interosseous membrane
- Vessels leaves the anterior compartment of the leg & becomes superifical & continues on the dorsum of the foot becoming the dorsal pedis artery

Anterior Tibial artery

20

Functions of the foot:

1. Supports body weight
2. Provides leverage for locomotion
3. Serves as a spring to absorb shock

21

- Found along the anterior aspect of the ankle & holds all of the tendons in place of the anterior leg muscles, anterior tibial blood vessels & the deep fibular nerve

Superior & inferior extensor retinacula of the foot

22

Holds the tendons of the lateral leg muscles & the motor branches of the superficial fibular nerve in place

Fibular retiacula

23

Found along the medial aspect of the ankle & holds the tendons of the deep posterior leg muscles, posterior tibial blood vessels & the tibial nerve in place

Flexor retinacula

24

Functions of the Plantar Aponeurosis

1.holds the parts of the foot together
2. Helps protect the plantar surface of the foot
3. Helps support the longitudinal arches of the foot
