The central nervous system, sometimes called the « coordinator, » consists of brain and spinal cord. It is responsible for understanding information received from the peripheral nervous system and sending « guidance information » back to various parts of the body.

Where are the effectors located?

peripheral tissue at the outer end of the efferent nerve pathway (away from the central nervous system). Effectors respond to nerve impulses in special ways. In humans, effectors can be muscles that contract in response to nerve stimulation or glands that produce secretions.

What does the central nervous system coordinate?

The central nervous system consists of the brain and spinal cord.It is called « central » because it combines information from the entire body and Coordinate the activities of the whole organism.

Where are the coordinates of the nervous system?

The cerebellum — also called « the cerebellum » because it looks like a smaller version of the brain — is responsible for balance, movement, and coordination.The pons and medulla, along with the midbrain, are often referred to as brain stem. The brain stem receives, sends and coordinates information from the brain.

Where are the receptors in the human nervous system?

Receptor is connected to the central nervous system through afferent nerve fibers. The peripheral regions or regions from which neurons within the central nervous system receive input are called receptive fields.

• The brain and spinal cord are the central nervous system.
• Nerves that run throughout the body make up the peripheral nervous system.

What is the main difference between the central nervous system and the peripheral nervous system?

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all nerves brain and spinal cord, and extends to other parts of the body, including muscles and organs.

3 What is the function of the central nervous system?

The central nervous system consists of the cerebrum, cerebellum, and spinal cord. The remaining neurons and associated cells distributed throughout the body form the PNS. The nervous system has three main functions: Sensory input, information processing, and motor output.

What activities in the body are controlled by the central nervous system?

Most systems and organs in the body control only one function, but the central nervous system does many jobs simultaneously.it controls All voluntary movements, such as talking and walking, and involuntary movements such as blinking and breathing. It is also at the heart of our thoughts, perceptions and emotions.

What are the 3 effectors?

The main types of effectors are activators and inhibitors.Examples of effectors are as follows: (1) allosteric effectors, (2) bacterial effectors, and (3) Fungal effector (eg apoplast effectors and cytoplasmic effectors).

What are the two effectors in the nervous system?

It is the organ that performs the nervous system response. There are two types of effectors, Muscles (also called « motor effectors ») and exocrine glands (also called « secretory effectors »). All effectors are stimulated by nerves, i.e. « innervated ».

What is a Nervous System Diagram?

The central nervous system is the body’s integration and command center. It consists of the brain, spinal cord, and the retina of the eye. The peripheral nervous system consists of sensory neurons, ganglia (clusters of neurons), and nerves that connect the central nervous system to the arms, hands, legs, and feet.

Is the sciatic nerve part of the peripheral nervous system?

The longest nerve in the human body is the sciatic nerve. It runs from the spinal cord in the lower back along the left leg to the toes of the left foot. Like the entire nervous system, the peripheral nervous system has two parts: sensory and motor sector.

What is the main function of the peripheral nervous system?

Peripheral nerves are located outside the brain and spinal cord.them Passing information between the brain and the rest of the body. The peripheral nervous system is divided into two main parts: Autonomic Nervous System (ANS): Controls involuntary bodily functions and regulates glands.

What does the peripheral nervous system consist of?

Overview. The peripheral nervous system refers to the parts of the nervous system outside the brain and spinal cord.it includes Cranial nerves, spinal nerves and their roots and branches, peripheral nerves and neuromuscular junctions.
