Pelvis and Upper Thighs Flashcards
The pelvis is made up of which bones?
Ilium, Ischium, and Pubis
Which bones form the **acetabulum **laterally and inferiorly?
Ilium, Ischium, and Pubis
Which bone is superior and the largest part of the pelvis?
Ilium
Which bones are known as the “sit” bones?
Ischial tuberosity
Which bone structure markings are located in the same coronal (frontal) plane of the pelvis?
Anterior superior iliac spine (ASIS) and pubic symphysis
Which bone structure markings are located in the same vertical (sagittal) plane in the pelvis?
**Anterior superior iliac spine (ASIS) **and pubic tubercle
What lies inferior and medial to the acetabulum?
Obturator foramen
What runs from the **anterior superior iliac spine **(ASIS) **to the pubis?
Inguinal ligament
What is the longest and heaviest bone in the body?
Femur
What is the femoral anteversion?
Head is angled ~14 degrees anteriorly to trochanters and distal condyles
What is the angle of inclination in the femur?
125 degrees
What is the purpose of the linea aspera?
Located in the posterior aspect of the femur and serves as an attachment for muscles.
What is the Great saphenous vein?
It is a very superficial vein that runs the length of lower extremity and is a vessel used for cardiac bypass surgery.
What descends through the femoeral triangle and enters the adductor canal?
Femoral artery
What passes deep to adductor magnus and moves posteriorly?
Deep femoral artery
What are the contents of the femoral triangle?
- Femoral nerve and its (terminal) branches
- Femoral sheath and its contents:
- *Femoral artery** and several of its branches.
3. Femoral vein and its proximal tributaries (e.g., the great saphenous and deep femoral veins).
4. Deep inguinal lymph nodes and associated lymphatic vessels.
The **femoral nerve **is formed from what?
Lumbar plexus L2-L4
The **femoral nerve **branches off what and innervates the what?
The cutaneous branch of the femoral nerve branches to become the **saphenous nerve **and it innervates the anterior thigh muscles.
What are the borders of the femoral triangle?
- Inguinal ligament
- Adductor longus
- Sartorius
What makes up the floor of the femoral triangle?
- Iliopsoas
- Pectineus
- Adductor longus
Where does the **adductor canal **begin and where does it end?
- BEGINS where S**artorius **crosses Adductor longus.
- ENDS at **Adductor hiatus **in the Adductor magnus tendon
What are the contents of the Adductor canal?
- Femoral artery and femoral vein
- Saphenous nerve
- Nerve to Vastus medialis
What is the action and innervation of the Psoas major?
ACTION: Hip flexion
INNERVATION: Branches of Lumbar Plexus
What is the action and innervation of the Iliacus?
ACTION: Hip flexion
INNERVATION: Femoral nerve
