Blood Supply Unit Three Exam Flashcards
Blood supply to individual vertebra is typically
Segmental
Once inside the foramen, the artery splits into what 3 main branches
Anterior branch, posterior branch and neural branch
What is AKA of anterior branch artery
Prelaminar branch
AKA of posterior branch artery
Postcentral branch artery
AKA of neural branch artery
Neurospinal branch artery
Where does the anterior branch artery supply blood to
Posterior aspect of the vertebral bodies and the anterior aspect of the spinal cord, anterior ligaments inside the spinal canal
The posterior branch artery supplies blood to
The posterior arch, posterior part of the spinal cord and ligaments in the posterior spinal canal
The neural branch artery supplies blood to
Lateral aspects of the spinal cord, spinal nerve and nerve roots
what are the three main arteries of the spinal cord
2 posterior spinal arteries and 1 anterior spinal artery
The spinal cord three main arteries goes from
The head/neck downward to supply the main portion of the spinal cord
The posterior spinal arteries and anterior spinal artery are branches from what
The vertebral artery before they unite together to form the basilar artery
The anterior spinal artery comes from
Both vertebral arteries, unites in the front of the spinal cord
When the anterior spinal artery begins to run caudally, it goes through what
Ventral median fissure of the cord
Between T9 and T12, a branch off the anterior spinal artery is called
Great radicular artery of adamkiewicz
The great radicular artery of adamkiewicz supplies blood to
Inferior thoracic vertebrae, superior lumbar vertebrae, lumbosacral enlargement of the spinal cord
The anterior spinal artery also supplies blood to
Lumbar segmental arteries, lateral sacral artery, and blood to the sacrum and coccyx
The posterior spinal artery arises from the
Vertebral artery, adjacent to the medulla oblongata
The posterior spinal artery supples what of the posterior columns of the spinal cord
Grey and white posterior columns
What are the two venous plexus
Internal venous plexus and external venous plexus
Where is the internal venous plexus located
On the inside of the spinal canal
Where is the external venous plexus located
Outside the vertebral column
The internal venous plexus is also called
Epidural venous plexus and batson’s plexus
The internal and external venous plexus can be subdivided into what
Anterior and posterior
The basivertebral vein is located where
Inside the vertebral body
The basivertebral body is part of
Anterior internal venous plexus
The opening in the vertebral body is called what
Hanh’s venous cleft
