Anatomy of Movement Control

Question 1

Lower Motor Neurons

Answer 1

alpha motor neurons- lowest level of motor control is performed, located in the spinal cord and the brain stem (midbrain, pons, medulla), partly under the control of sensory input which can lead to the generation of reflexes

Question 2

Pattern generation mechanisms

Answer 2

the output of alpha neurons can be organized into these which organize rhythmic activities such as winged flight, locomotion, or chewing

Question 3

Upper Motor Neurons

Answer 3

these originate in the motor areas of the frontal lobe in the neocortex, control alpha motor neurons

Question 4

Motor relateds areas in the neocortex in the frontal lobe

Answer 4

Primary motor cortex- near the central sulcus
Premotor cortex
Supplementary motor cortex
Prefrontal cortex
