Lower Motor Neurons

Question 1

How are LMNs distributed to muscles?

Answer 1

Via peripheral (spinal) nerve

Question 1

Where are the cell bodies of LMNs located?

Answer 1

Grey matter of ventral horn

Question 2

The LMNs are thick and heavily myelinated. (T/F?)

Answer 2

TRUE

Question 3

Where are the cell bodies of neurons innervating axial musculature, such as postural trunk muscles, located compared to those innervating appendicular (limb) musculature?

Answer 3

Those innervating axial musculature are located medially within the ventral horn, whereas those innervating appendicular musculature are located progressively more laterally.
