The muscle fibers are functionally organized as motor units. A motor unit consists of a single motor neuron and all of the muscle fibers it innervates.
Whole muscles exhibit characteristics that are more complex than those of individual muscle fibers or motor units. Instead of responding in an all-or-none fashion, whole muscles respond to stimuli in a graded fashion, which means that the strength of the contractions can range from weak to strong.

What controls voluntary movements?

Voluntary movements are controlled by the motor cortex in the brain, which sends signals to the muscles through the spinal cord and peripheral nervous system. The cerebellum also plays a key role in coordinating and fine-tuning these movements to ensure smooth and precise execution. Feedback from sensory receptors helps in adjusting and refining movements as needed.


Functions of the cerebrum?

The cerebrum is responsible for functions such as higher brain functions like thinking, memory, and learning. It also controls voluntary movements and interprets sensory information. Additionally, the cerebrum plays a role in emotions and decision-making.


What is the difference between two parts of the PNS?

The peripheral nervous system (PNS) consists of the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and transmits sensory information, while the autonomic nervous system regulates involuntary functions like heart rate and digestion.


What is the function lateral corticospinal and anterior corticospinal?

The lateral corticospinal tract controls voluntary movements of the limbs by transmitting signals from the brain to the spinal cord. The anterior corticospinal tract also helps regulate voluntary movements but primarily controls fine movements of the limbs and trunk. Both tracts are part of the corticospinal pathway responsible for motor function.

Which system controls voluntary movements such as throwing the ball catching the ball kicking the ball?

The somatic nervous system controls voluntary movements, including actions like throwing, catching, and kicking a ball. It is a part of the peripheral nervous system and is responsible for transmitting signals from the central nervous system to skeletal muscles, enabling deliberate motor actions. Through motor pathways, it allows for precise coordination and control of these movements.
