Solution
The second neurons in the efferent motor pathway, also known as lower motor neurons, have axons that can synapse to:
-
Skeletal muscles: These neurons can synapse with skeletal muscles to control voluntary movements.
-
Gland cells: Although the efferent motor pathway primarily controls muscle movements, it can also influence gland cells indirectly. However, this is typically through the autonomic nervous system, not the somatic motor system.
-
Cardiac muscles: The efferent motor pathway does not directly control cardiac muscles. The autonomic nervous system, specifically the sympathetic and parasympathetic systems, control the heart rate.
-
Smooth muscles: Similar to cardiac muscles, smooth muscles are primarily controlled by the autonomic nervous system, not the efferent motor pathway.
So, the correct answer is Skeletal muscles.
