Week 6 - Vertebral Column, Anteromedial Thigh, Osteology of the Lower Limb Flashcards
Name the movements of the vertebral column.
- Flexion and extension
- Lateral flexion
- Rotation
Outline the gross functions of the vertebral column.
- Project weight of body to pelvis and lower limbs (centre of gravity)
- Attachment for bones - Supports the skull and the ribs (maintains the balance between the rib cage and the thoracic cavity)
- Attachment for muscles - of the trunk, very strong, maintain erect posture, move the vertebral column, attachment for muscles of the pelvic and pectoral girdles
- Protection and passage of spinal cord
- Shock absorption
- Segmental innervation of the body
Which tarsal bone articulates with the leg bones?
Talus
Which muscle is used as a surface landmark for a femoral artery puncture?
Sartorius
What are the three muscles that insert onto the pes anserinus (literally goose’s foot: anteromedial aspect of the tibia)?
- Sartorius
- Gracilis
- Semitendinosus
What is the main innervation for the muscles of the anterior thigh? What are the psoas muscles innervated by?
- Femoral nerve: L2, L3, L4
2. Psoas muscles are innervated by the anterior rami of lumbar nerves
Which of the adductor muscles acts as both an adductor and a hamstring muscle? Describe its innervation.
Adductor magnus
Adductor part: Obturator nerve
Hamstring part: Tibial nerve
What structure does the femoral sheath NOT enclose?
Femoral nerve
What structures does the femoral sheath enclose?
- Femoral artery
- Femoral vein
- Lymph vessels
What procedures can the femoral pulse be used for?
- Femoral stab
2. Angiography
Why is cannulation of the femoral vein important?
Central access for drugs
What types of nerve block are possible in the thigh region?
Femoral nerve and fascia iliac block
What can the femoral hernia protrude into?
Femoral canal
