Back Angiology And Neurology Flashcards
The superficial branch of the transverse cervical artery travels with what?
The spinal accessory nerve along the deep surface of the trapezius muscle
If the deep branch of the transverse cervical artery is present, it replaces which artery?
Replaces the dorsal scapular artery traveling along the medial border of the scapula supplying the levator scapulae and rhomboid muscles
What does the dorsal scapular artery supply?
Levator scapulae and rhomboid muscles
If it arises from the transverse cervical artery it is known as the deep branch of that artery
What muscle does the thoracodorsal artery supply?
Latissimus dorsi
Which arteries are known to be arterial sources for the production of paraspinal arteries?
Vertebral artery, ascending cervical, deep cervical, posterior intercostal, subcostal, lumbar, iliolumbar and lateral sacral arteries
What is the significance of the paraspinal arteries?
Supply the vertebra, spinal cord and surrounding structures and feed directly into the anterior and posterior spinal arteries especially in regions of the cervical and lumbar enlargements of the spinal cord to assist the very small spinal arteries in supplying the spinal cord
What are the four main branches of the paraspinal arteries?
Dorsal, equatorial, periosteal and spinal branches
Which arteries are apart of the spinal branch of the paraspinal arteries?
Anterior and posterior vertebral canal, anterior and posterior radicular, anterior and posterior segmental medullary, and great anterior segmental medullary arteries
Which three paraspinal arterial sources are from the descending aorta?
Posterior intercostal, subcostal and lumbar arteries
Which two paraspinal arterial sources are from the internal iliac artery?
Iliolumbar and lateral sacral arteries
Which paraspinal artery is from the costocervical trunk?
Deep cervical artery
Which paraspinal artery is from the inferior thyroid artery?
Ascending cervical artery
Which paraspinal artery is from the subclavian artery?
Vertebral artery
What are the two main plexuses of spinal veins?
External and internal vertebral venous plexuses
Which two arteries from the spinal branch of paraspinal arteries does not directly feed into the anterior/posterior spinal arteries?
Anterior and posterior radicular arteries
Complete transection of the spinal cord results in what?
Loss of sensation and motor function below the lesion
What is the result of a spinal injury at C1-3?
No function below the head, respirator necessary for life
What is the result of a spinal cord injury at C4-5?
No function of limbs, respiration capable
