Answer to Question #115076 in Cell Biology for mike

Question

Describe how skeletal muscle allows for both fine motor movement (like picking up a pencil and writing) and gross motor movement (like moving a piece of furniture across the room).

Answer 1

It depends from different neuronal regulation.

Fine motor skill (or dexterity) is the coordination of small muscles, in movements—usually involving the synchronisation of hands and fingers—with the eyes. The complex levels of manual dexterity that humans exhibit can be attributed to and demonstrated in tasks controlled by the nervous system.

It regulated by cerebellum.

Gross motor movement- regulated by basal ganglions
