Q

What is the function and nerve supply for the articularis genus muscle

A

Pull the synovial membrane of the knee joint upward during knee extension, preventing it from being pinched or compressed between the femur and patella.
Protect the joint capsule by maintaining its proper position during knee movements.

Innervated by the femoral nerve

Q

What is the Westphals sign

A

Refers to a decreased or absent patellar tendon reflex, also known as the knee-jerk reflex.

This reflex is tested by tapping the patellar tendon below the kneecap, which should normally cause the leg to extend

23
Q

What is the origin and insertion of the medial compartment of the thigh

A

Origin :on the pubis
Insertion: linea aspera of the femur
Except Gracillis which insertys at the Medial aspect of the proximal part of the tibia

24
Q

What is the function of the proximal and lateral fibres of the medial compartment

A

The proximally inserting fibers contribute to lateral rotation.
Distally-inserting fibers contribute to medial rotation.

25
Whats the function of the Hamstring muscle
extensors of the thigh at the hip and flexors of the leg at the knee,
26
What is the individual function of the biceps femoris
Biceps femoris is a lateral rotator of the leg and thigh,
27
Which muscles of the hamstrings serve as medial rotators
semimembranosus and semitendinosus can serve as medial rotators of the leg
28
What nerve supplies the Hamstrings
The tibial branch of the ciatic nerve, Except the short head of the biceps femoris, which is innervated by the common fibular nerve
29
Which group of muscles are the pes anserinus
The pes anserinus consists of the conjoined tendons of the sartorius, gracilis, and semitendinosus muscles ## Footnote It inserts into the proximomedial tibia and acts as a secondary valgus restraint augmenting the medial supporting structures of the knee.
30
What is the function of the pes anserinus muscles
The pes anserinus stabilizes the medial side of the knee, particularly during activities like walking and running. It assists in flexion and medial rotation of the knee when the knee is flexed.
31
What is the name of the deep fascia of the leg
Crural Fascia
32
What innervates the anterior compartment of the leg
Deep fibular nerve
33
What is the action of the lateral compartment of the leg
Eversion of the foot and assist in plantar flexion
34
What nerve supplies the lateral compartment of the leg
Superficial fibular nerve
35
What are the vestigial muscles of the leg
Plantaris muscle Fibularis(peroneal tertius) muscle
36
What is the gastrocnemius and soleus muscles collectively reffered to
Triceps surae muscle, Theyre the main plantar flexors of the foot
37
Other function of the gastrocnemius
Power flexor of the leg
38
Whats muscle is responsible for unlocking the extended knee
Popliteus muscle
39
What is femoral hernia
When a loop of the intestine protrudes into the femoral canal
40
Fibularis brevis
BAse of the fifth metatarsal
41
Fibularis Longus
The fibers of the fibularis longus muscle travel inferiorly to the foot and insert, via a long tendon, onto the: - plantar surface of medial cuneiform bone; - plantar aspect of the base of first metatarsal bone.
42
43
Tom Dig And Harry
tibialis posterior Tendon Flexor digitorum longus Artery and nerve Flexor Halluicic longus
44
What are the borders of the Femoral Triangle
SUPERIOR BORDER: INGUINAL LIGAMENT LATERAL BORDER: SARTORIOUS MUSCLE? MEDIAL BORDER: ADDUCTOR LONGUS MUSCLE
45
Illiotibial tract
Thickening of the lateral side of the thigh
46
What is the trendelenburg sign
The Trendelenburg sign is a physical examination that tests for weakness in the hip abductor muscles, primarily the gluteus medius and gluteus minimus.
47
What is the mechanism for the Trendeleburg sign
A patient is made to stand on one leg with the other leg unsurported The Abductors of the hip(gluteus madius and minimus) are to contract to prevent the pelvis from sagging on the unsurpoted leg A sagging hip on the unsupported leg is indicative of a positive Trendeleburg sign and a weakenig in the hip abductors
48
Anatomically and functional what parts of the body does the gluteal region belong to
It is Anatomically part of the Trunk but functionally considered as part of the lower extremity
49
What is the innervation of the skin of the gluteal region
The cluneal nerve
50
What are the boundaries of the gluteal region
Superiorl : Iliac Crest Medially: intergluteal cleft Laterally the greatertrochanter Inferiorly the gluteal fold
51
What is the action of the Gluteus maximus
primarily abductors, extensors and lateral rotators of the thigh
52
What is the powerful extensor of the thigh
Gluteus maximus
53
What is the innervation and blood supply of the Gluteus maximus
inferior gluteal nerve Blood supply from both inferior and superior gluteal arteries
54
What is the innervation and blood supply of the gluteus medius and gluteus minimus and tensor fascia latae
Superior gluteal nerve Superior Gluteal artery
55
What is the function of the gluteus medius and minimus
Theyre abductors of the hipjoint
56
Where is an IM(Intramuscular injection given in the buttocks, and why
Given at the upper outer quadrant of the buttocks To avoid injecting into the sciatic nerve
