The nervous system controls all of the responses and activities within a horses behavior.
The nervous system is connected to the brain and the spinal cord, the brain sends messages through the spinal cord and to muscles.
The nervous system co-ordinates most of the bodies internal functions. For example, it controls digestion, respiration, the contractions of the heart and of smooth muscles in blood vessels, and the release.
When an animal is born, it is born with all of the neurons it will ever have.
A horse’s shape and size varies with the placement of the nervous system, but most neurons still contain the same parts.
Other than nerve cells, the nervous system also has a collection of glial cells. These cells control the speeds of the signals. They also help sustain the nerve cells, provide nutrients, get rid of unwanted chemicals, and they stimulate the growth of axons.
The Central Nervous System is the center of all nervous control. It consists of the brain and spinal cord. The brain is located in the cranial cavity. And the spinal cord is located in the vertebral/spinal column.
The Autonomic Nervous System is part of the Peripheral Nervous System. It controls the involuntary systems such as the circulatory system (heart), respiratory system (lungs), etc.The Autonomic Nervous System has two major systems: Sympathetic and Parasympathetic.
