Flashcards in Fascia/Connective Tissue MD3 Deck (22):
1

Brachial Fascia

Antebrachial Fascia

Bicipital Aponeurosis

bicipital aponeurosis reinforces the cubital fossa & protects the brachial aa & median nn esp. during venipuncture

2

Annular ligament of Radius

keeps radius in the radial notch of ulna

3

Transverse Humeral ligament

runs from greater to lesser tubercle

encloses tendon of long head of biceps in the intertubercular groove

4

Interosseus Membrane

separates ant. & post. forearm compartments, transfers forces b/w radius, ulna, humerus, attachment site of forearm muscles

5

Flexor Retinaculum

Palmar Carpal Ligament

Palmar Carpal Ligament: thickening of antebrachial fascia @ wrist, covering palmaris longus tendon, ulnar aa & nn

Flexor Retinaculum: roof of carpal tunnel w/ median nn, from triquetrum, pisiform & hook of hamate to trapezium & scaphoid, origin of thenar eminence muscles, ulnar nn & aa run above it

6

Carpal Tunnel

Roof: flexor retinaculum, Floor: carpal bones

transmits median nn, tendons of flexor pollicis longus, flexor digitorum profundus & superficialis

7

Palmar Aponeurosis

protects superficial palmar arterial arch, long flexor tendons, palmar digital nn

8

Extensor Retinaculum

holds extensor muscle tendons in place

9

Radial Collateral Ligament

Ulnar Collateral Ligament

RCL (wrist): styloid process of radius to scaphoid

UCL (wrist): styloid process of ulna to pisiform & triquetrum

10

Vincula Longus & Brevis

attach FDP & FDS tendons to phalanges

11

Suprascapular Ligament/Transverse Scapular Ligament

turns scapular notch into a foramen

suprascapular nn runs under it, suprascapular aa runs above it

12

Glenoid Labrum

connective tissue around rim of glenoid cavity providing more area for humeral head

13

Axillary Sheath

fibrous sheath surrounding and protecting brachial plexus, axillary aa & vv

14

Superior & Inferior Extensor Retinaculum

15

Superior & Inferior Peroneal Retinaculum

16

Ligaments of Hip

Iliofemoral

-strongest, Y shaped

Pubofemoral

Ischiofemoral

-weakest

 

-wind up and prevents hip extension

 

Ligament of the head of the femur

-weak support, transmits blood vessel to head of femur

17

Extracapsular Ligaments of Knee

Patellar lig.

-continuation of quadriceps tendon, used in ACL reconstruction

Medial Collateral lig.

-weak, flat band, prevents valgus stress

Lateral Collateral lig.

-cord like, prevents varus stress

Arcuate Popliteal lig.

 

Oblique Popliteal lig.

-prevents hyperext & lateral rotation of knee

18

Intraarticular Ligaments of Knee

Anterior Cruciate Lig.

-weaker, less blood supply, prevents anterior translation of tibia vs femur, prevents internal rotation of femur vs tibia, prevents hyperextension

Posterior Cruciate Lig.

-stronger, prevents posterior translation of tibia, prevents hyperflexion

19

Mensici

crescent shaped plates of fibrocartilage involved in shock absorption

medial meniscus

larger, less mobile, more injured

lateral meniscus

smaller, more mobile, less injured

transverse lig. of knee

attaches to anterior of both menisci, keeps them together during movement

20

Ankle Ligaments

Medial (Deltoid) lig.

-anterior & posterior tibiotalar, tibiocalcaneal, tibionavicular

-resists overeversion, supports medial longitudinal arch

 

Lateral lig.

-anterior & posterior talofibular, calcaneofibular

-prevents inversion (ankle sprain)

21

Spring Ligament (Plantar Calcaneonavicular) lig.

22

transverse acetabular lig. -> ligamentum teres

lunate surface (articulates w/ head of femur)
