The central nervous system (CNS) lies within a series of protective bones: the brain inside the skull, and the spinal cord in the vertebrae that make up the spine. The peripheral system comprises the nerves. The brain is a very complex organ with many parts. A horse’s brain is similar in shape and function to that of other mammals.

How is a horse’s brain different from a human brain?

The horse has a far smaller ratio of brain size to body size than the human. The human brain is able to think in the past, present and future and controls memory, communication and association. The horse’s brain, however, is mainly busy with muscle coordination, balance and body functions. A horse is not able to reason through a skill.

What are the components of the nervous system?

From an anatomical perspective the nervous system is made up of the Central Nervous System (CNS) (brain and spinal cord), and Peripheral Nervous System (PNS) (cranial and peripheral nerves), and from a functional perspective it is divided into the Somatic Nervous System (voluntary movement), and the Autonomic Nervous System (ANS), which controls…

What are the three parts of a horse’s brain?

Like the brains of all mammals, the horse’s brain is divided anatomically into three sections: the hind-brain, the mid-brain and the fore-brain. The hind-brain consists of the brainstem (literally the ‘stalk’ of the brain) through which pass all the nerve fibres that relay signals from the spinal cord.

Are horses left or right-brained?

Rats, considered to be on the lower end of the intelligence scale of mammals (although rat owners will surely disagree), have smoother brain surfaces than horses. In turn, horses have fewer fissures in their brains than primates.

What is the shape of a horse’s brain?

As prey animals, horses must be born much more “ready for life” than humans—they’re able to stand and move just after birth. A fatty substance in the brain called myelin acts as an insulator and coats nerve fibers to help the transfer of information, which allows for rapid brain growth and maturation.
