Back and spinal cord Flashcards
Where is the body of a vertebrae
The big flat bit connected to the rest via pedicles
What are pedicles of vertebrae?
The bridges between the body and the transverse/spinous processes
What are the superior articular processes
The lumps between the transverse processes and the pedicles
What are the transverse processes
the bits that jut out to the side on the posterior
What is the spinous process
THe single bit that juts out perpendicular to the body
What are the lamina
connects the transverse process and spinous process
Is the dorsal root relating to sensory information or motor
Sensory
Is the ventral root relating to sensory or motor information
motor
What are the 2 types of nevre from the ventral root
Somatic and autonomic nerves
What are the 3 masses of erector spinae
iliocostalis, longissimus thoracis, iliocostalis thoracis and lumborum together
What is the most lateral mass of the erector spinae
iliocostalis
What is the middle mass of the erector spinae
longissimus thoracis
What is the most medial mass of the erector spinae
spinalis
Where do the short rotators of the spine insert/originate
Transverse process to base of spinous process 1 above
Where do the long rotators of the spine insert/originate
transverse process to base of spinous process 2 above, skipping a vertebrae
