Nerve Cells and Nervous Systems pp Cite as. The essence of nervous system function is control by means of communication. Unicellular acellular organisms, such as Amoeba or Paramecium , can perform every function necessary to sustain their lives. They can take in nutrients from their external environment, organize their metabolic reactions, excrete waste products and move towards or away from objects in their external environment; that is, they can perform simple behavioural adjustments. These actions are performed without the aid of a nervous system as such. In multicellular organisms more complex than sponges the constituent cells have become specialised into organs and tissues for carrying out specific functions, such as digestion and assimilation of foodstuffs, respiration, circulation of the blood to carry oxygen, metabolites and hormones to and from the tissues, reproduction and so on.

Endocrine systems, also referred to as hormone systems, are found in all mammals, birds, fish, and many other types of living organisms. They are made up of:. Hormones act as chemical messengers that are released into the blood stream to act on an organ in another part of the body. Although hormones reach all parts of the body, only target cells with compatible receptors are equipped to respond. Over 50 hormones have been identified in humans and other vertebrates. Hormones control or regulate many biological processes and are often produced in exceptionally low amounts within the body. Examples of such processes include:.
One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. The hypothalamus is located below the thalamus and is part of the limbic system. All vertebrate brains contain a hypothalamus. In humans, it is the size of an almond.
Homeostasis Homeostatic mechanisms help organisms to keep their internal body conditions near constant Three key homeostatic mechanisms are: Thermoregulation — the control of body temperature Osmoregulation — the control of the water potential of body fluids The control of blood glucose concentration These homeostatic mechanisms in mammals require information to be transferred between different parts of the body There are two coordination systems in mammals that do this: The nervous system The endocrine system. The nervous system The human nervous system consists of: The central nervous system CNS — the brain and the spinal cord The peripheral nervous system PNS — all of the nerves in the body It allows us to make sense of our surroundings and respond to them and to coordinate and regulate body functions Information is sent through the nervous system as nerve impulses — electrical signals that pass along nerve cells known as neurones A bundle of neurones is known as a nerve Neurones coordinate the activities of sensory receptors eg. The endocrine system A hormone is a chemical substance produced by an endocrine gland and carried by the blood They are chemicals which transmit information from one part of the organism to another and bring about a change They alter the activity of one or more specific target organs Hormones are used to control functions that do not need instant responses The endocrine glands that produce hormones in animals are known collectively as the endocrine system A gland is a group of cells that produces and releases one or more substances a process known as secretion. Endocrine glands have a good blood supply as when they make hormones they need to get them into the bloodstream specifically the blood plasma as soon as possible so they can travel around the body to the target organs to bring about a response Hormones only affect cells with receptors that the hormone can bind to These are either found on the cell surface membrane, or inside cells Receptors have to be complementary to hormones for there to be an effect. Cell Structure 1.
The main function of endocrine glands is to secrete hormones directly into the bloodstream. Hormones are chemical substances that affect the activity of another part of the body target site. In essence, hormones serve as messengers, controlling and coordinating activities throughout the body. See also Endocrine Glands. Upon reaching a target site, a hormone binds to a receptor, much like a key fits into a lock. Once the hormone locks into its receptor, it transmits a message that causes the target site to take a specific action. Hormone receptors may be within the nucleus or on the surface of the cell.
The peripheral nervous system is comprised of the somatic and autonomic nervous systems. The somatic nervous system transmits sensory and motor signals to and from the central nervous system. The autonomic nervous system controls the function of our organs and glands, and can be divided into the sympathetic and parasympathetic divisions. Sympathetic activation prepares us for fight or flight, while parasympathetic activation is associated with normal functioning under relaxed conditions.
In biology , the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. The CNS consists of the brain and spinal cord. The PNS consists mainly of nerves , which are enclosed bundles of the long fibers or axons , that connect the CNS to every other part of the body.
The nervous system uses two types of intercellular communication—electrical and chemical signaling—either by the direct action of an electrical potential, or in the latter case, through the action of chemical neurotransmitters such as serotonin or norepinephrine.
Neurosecretory cell , a type of neuron , or nerve cell, whose function is to translate neural signals into chemical stimuli. Such cells produce secretions called neurohormones that travel along the neuron axon and are typically released into the bloodstream at neurohemal organs, regions in which the axon endings are in close contact with blood capillaries. Neurosecretory cells are present in most multicellular animals and are usually distinguished from other neurons by the unusually large size of the cell nucleus, axon endings, and the cell itself.
