The key difference between afferent and efferent neuron is that the afferent neurons carry nerve impulses from the sensory organs to the central nervous system while the efferent neurons carry nerve impulses from the central nervous system to the muscles. The nervous system is the director of all body activities. Its major functions include communication among the body parts and controlling of the body. Also, the nervous system comprises two major cells namely neuron and neuroglia. The neuron is the structural and functional unit of the nervous system. They are specialized cells which respond to chemical and physical stimuli and to conduct messages throughout the body.

The director and regulator of all the body activities whether small or big is nervous system. The main and major functions of nervous system are control and communication. The nervous system is built from two main cells which are named as neuron and neuroglia. The neuron is considered to be the structural and functional unit of the nervous system. These cells are specialized to respond to chemical and physical stimuli and to carry and transfer messages all over the body. Normally a human brain can direct more than 10 billion neurons at all the times.

Afferent neurons carry sensory signals from the body to the brain, they can be considered the “input” neurons for the brain. What is the main and most significant difference between afferent and efferent motor neurons? What is the difference between sensory neuron and a motor.

Afferent and efferent arterioles are responsible for the supply of blood to the glomerulus of the kidney. The main difference between afferent and efferent arterioles is that afferent arterioles carry blood to the glomerulus whereas efferent arterioles take the blood away from the glomerulus. An afferent arteriole is a branch of the renal vein, which carries blood containing nitrogenous wastes. An efferent arteriole is a branch of the renal artery, which carries filtered blood back to the circulation. The blood pressure of the afferent arteriole is high, facilitating the ultra-filtration of blood plasma at the glomerulus. Since most of the water content and small molecules are filtered out, the blood pressure of the efferent arteriole is less than that of the afferent arteriole. Afferent arterioles are branches of the renal vein, approaching the proximal portion of the nephron.

Afferent and efferent neurons connect the central nervous system CNS to produce a signal transmission pathway, which coordinates functions in the body. The CNS is composed of the brain and the spinal cord. Both afferent and efferent neurons belong to the peripheral nervous system PNS. Afferent neurons are also known as sensory neurons , and efferent neurons are also known as motor neurons. However, the effect stimuli and the responses of sensory and motor neurons are slightly different from that of afferent and efferent neurons. Sensual perceptions of the body are eye, nose, ear, tongue, and skin.

There are two main divisions in the peripheral nervous system — the afferent division and the efferent division. In this article, we will explore the differences between the components of these divisions — afferent and efferent neurons. Afferent neurons carry information to the brain and spinal cord for analysis. Afferent neurons comprise afferent systems, also known as sensory systems, because they are activated by external stimuli and convey the information to the area of the brain that is responsible for processing a particular stimulus. Efferent neurons carry information out of the brain. In the peripheral nervous system, they are usually referred to as motor neurons, because most of them carry information from the spinal cord to the various muscles; in addition, they go pretty much to every organ in the body.

Patients with spinal cord injury have deficits in their motor and sensory systems. What exactly does that mean from a biological point of view? Our nervous system - a complex machine Our nervous system is divided into two parts. The central nervous system includes the brain and the spinal cord. The peripheral nervous system consists of a network of neurons, which spans the organs, the muscles and the body.
