Oct 26, 2023 · This almond-sized part of the brain does a ton of work to regulate our bodies, earning the nickname 'master switchboard.'
Mar 17, 2023 · The brain is an organ composed of nervous tissue that commands task-evoked responses, movement, senses, emotions, language, communication, thinking, and memory. The three main parts of the human brain are the cerebrum, cerebellum, and brainstem. See Image. Human Brain, Encephalon.

There are four main areas in the brain: The cerebrum (the outer layer is called the cerebral cortex), which is split into two hemispheres and is highly folded. It controls intelligence ...
Nov 9, 2023 · The human brain is a complex organ, made up of several distinct parts, each responsible for different functions. The cerebrum, the largest part, is responsible for sensory interpretation, thought processing, and voluntary muscle activity.

The nervous system in a human is made of the brain, spinal cord, sensory organs and all the neurons that serve as communication channels between the various organs of the body. It is primarily made of a single type of cell called the neuron.Colloquially, they are also called nerve cells. Neurons are made of a central cell body and a number of exten...
Coordinating Movement of the Body Parts
The primary function of the nervous system is to receive information and to generate a response to a given stimulus. The information and the response could be simple, subtle or complex. For instance, when a hot object is touched, its temperature is conveyed quickly to the central nervous system and the response is an immediate reflex of removing the hand, through the action ofskeletal muscles. A few such incidents could also lead to the formation of learning and long-term memory encoded as a...
Perceiving and Responding to the Senses
Among the primary modes of input into the nervous system are the electrical impulses that arise from sense organs. Touch, sound, sight, smell, and taste are conveyed to the nervous system, in order to integrate information and assess the nature of the external world. Similarly, a number of neurons act as sensors for the internal state of the body. For instance, sensory neurons in the eyes, nose, and tongue can inform a person about the presence of delicious food, and create a desire to eat. A...
Higher Thought and Processing
Thus, while the nervous system can be considered as the center for receiving, processing and transmitting information, its functions are complex in most organisms. In humans, it is important for thought, reasoning, language, perception, and speech.Parts of the central nervous system control voluntary and involuntary muscle movement, and even peristalsis and digestive movement. It is important for the maintenance of balance, internal temperature regulation, and circadian rhythms. The rate of b...
The anatomy of the nervous system in humans consists of the brain and spinal cord, along with the primary sense organs and all the nerves associated with these organs. The brain and the spinal cord form the central nervous system (CNS).All other neuronal tissue is brought under the umbrella of the peripheral nervous system (PNS). Therefore, the PNS...
The nervous system is an enormously complex system for coordinating an animal’s behavior and helping it navigate and react to the outside environment. In the least complex organisms, the nervous system can consist of only a few neurons and no central brain. At the other end of the spectrum, the human brain is capable of complex thought, symbology, ...
The nervous system can be attacked by infectious pathogens – bacteria, viruses, fungi or protozoans. Bacterial infections such as tuberculosis or syphilis can colonize nervous tissue as a secondary site of infection in advanced stages of the disease. The meninges covering the central nervous system are particularly susceptible to infection,especial...
Jul 26, 2017 · The thalamus acts as the “switchboard” for the cerebral cortex. All sensory information except for smell passes through the thalamus before it goes on to the cerebral cortex processing centers.
The structure and function of the nervous system. The nervous system enables humans to react to their surroundings and to coordinate their behaviour. It comprises millions of neurones and uses ...
