Lower extremities and hip Flashcards
Name the lower limb bones
Hip bone
Ischium
Femur
Patella
Tibia
Fibula
Calcaneus
Metatarsals
Proximal and distal phalanges
Name the two sections that the hip bone contains
Ileus crest
Tubercular
What does the femur connect to?
Hip bone
What does the femur do?
Protects the femur
Describe the shape of the femur
At the front it is rounded and at the back it is a triangular shape to allow the hamstring to attach itself to the back of the femur.
Name the 4 muscles of the quadriceps
Rectus femoris
Vastus lateralis
Vastus medialis
Vastus intermedius
Describe the rectus femoris
Spans from the hip bone down to the patella.
As it spans two different joint it can be involved in two different movements.
Hip: flexion
Knee: extension
Superficial muscle
Describe the vastus lateralis
Located on the medial side of the rectus femoris
Attaches itself to the femur and to the lateral part of the patella.
Involved in extension of the knee.
Superficial muscle.
Describe the vastus medialis
Located on the medial side of the thigh.
Involved in extension of the knee
Superficial muscle
Describe the vastus intermedius
Attaches itself to the top end of the femur and the patella
Creates extension of the knee
Name the 4 adductors of the lower extremities
Adductor longus
Adductor brevis
Pectineus
Gracilis
Describe the adductor longus
Moves leg towards the midline of the body.
Lies on the medial side of the thigh.
Insertion point is on the pubic bone.
It spans out towards the medial side of the femur. When it contracts it pulls the leg in towards the body.
Describe the pectineus
Attach themselves to the pubic bone and span out to midway up the femur.
Creates inwards rotation
Describe the Gracilis
Attaches itself to the medial side of the femur
Name the adductor of the lower extremities
Sartorius
Describe the sartorius
Located in the distal part of the leg.
Starts off at the anterior superior iliac spine then crosses the quads towards the inside and attaches itself to the bottom of the femur head.
When it contracts it pulls the leg outwards.
Name the muscles that make up the iliopsoas
Psoas major
Iliacus
Describe the psoas major
Involved in flexion of the hip
Attaches itself to the bottom of the spine and below the head of the femur.
Describe the iliacus
Attaches itself to the ileus crest and below the head of the femur.
When it contracts it causes flexion of the hip.
Name the two proximal muscles of the gluteal region
Abductors
Hamstrings
What are the abductors in the gluteal region involved in?
Abduction of the hip.
Moving the leg away from the midline of the body.
What are the hamstrings in the gluteal region involved in?
Extension of the hip and flexion of the knee.
Name the abductor muscles of the gluteal region
Gluteus medius
Gluteus minimus
Piriformis
Tensor fascia Latae
