They can’t name an object on the left hand side but they can if it is on the right hand side because vision is processed on the opposite side

Question 23

What are the 2 enlargements of the spinal cord ?

Answer 23

Cervical enlargement - provides innervation for upper limbs via brachial plexus

Lumbar enlargement- provides innervation of lower limb by lumbar plexus and sacral plexus

Question 24

What effect does the different lengths of the vertebral canal and spinal cord cause ?

Spinal cord segments are not adjacent to their vertebral bodies - apart from cervical region

Question 25

What is the denticulate ligament ?

Answer 25

Flat membranous continuation of pia mater

Question 26

Why do higher levels of the spinal cord contain more white matter ?

Thoracic and upper lumbar

Contains preganglionic sympathetic neurons
