Reproductive hormones affect the development of the nervous system. Key Takeaways Key Points The peripheral nervous system PNS provides the connection between internal or external stimuli and the central nervous system to allow the body to respond to its environment. The spinal cord connects the brain and brain stem to all of the major nerves in the body. Cardiovascular System. It consists of nerves in cardiac musclesmooth muscle, and exocrine and endocrine glands. Learning Objectives Discuss the organization of the peripheral nervous system. The cerebellum is located underneath the backside of the cerebrum, and governs balance and fine motor movements. Anatomical terminology [ edit on Wikidata ]. The central nervous system includes the spinal cord and the brain. The singular example of a monosynaptic reflex is the patellar reflex.
(Brain) Precentral gyrus: the origin of nerve signals initiating movement.

The Nervous System and Skeletal System! by janiece barber on Prezi
The nervous system can be broken down into two major parts—the central nervous system and the peripheral nervous system.
It increases physical arousal levels, raising the heart and breathing rates and dilating the pupils, as it prepares the body to run or confront danger. In turn, alpha motor neurons relay the stimuli received down their axons via the ventral root of the spinal cord.
This article needs additional citations for verification. It extends from the brain stem through the spine, with nerves branching off to various parts of the body.

How is the nervous system connected to the skeletal system in the human body Socratic
The nervous system can be broken down into two major parts—the central nervous system and the peripheral nervous system. An example of a polysynaptic reflex arc is seen when a person steps on a tack—in response, their body must pull that foot up while simultaneously transferring balance to the other leg.
A reflex arc is a neural circuit that creates a more or less automatic link between a sensory input and a specific motor output.

The ventral root has motor efferent fibers that transmit messages from the central nervous system to the effectors, with the cell bodies of the efferent fibers found in the spinal cord gray matter.

|The nervous system regulates the speed at which food moves through the digestive tract.
The brain stem is connected to the underside of the brain. The central nervous system, the main data center of the body, includes the brain and spinal cord. The cerebellum is located underneath the backside of the cerebrum, and governs balance and fine motor movements.
The CNS is the main control center of the body—it takes in sensory information, organizes and synthesizes this input, then provides instructions for motor output to the rest of the body.
