Phlebotomy And Pathophysiology

The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let 's take a look at the central nervous system.

The nervous system is made up of basic units called neurons. The main role of the neurons is to receive, integrate and transmit information throughout the body. There are some neuroglial cells found in nervous system aswell which provide support to the neurons by giving protection and nourishment Neurons have nerve processes that looks like finger like projections extended from the nerve cell body. They also contain axons and dendrites which enable them to transmit signals throughout the body. Normally, axon carry signals away from the cell body and dendrites carry signals toward the cell body according to Regina Bailey (2013). Neurons have three different shapes: bipolar, unipolar and multipolar where bipolar has two neuronal processes coming out of the cell body, unipolar has only one neuronal process coming out of the cell body and multipolar has many neuronal processes coming out of the cell body.

Neurons are information- processing units in the central nervous system that receive and transmit information. It is made up of an axon, dendrites and a cell body. The nucleus and cytoplasm are contained in the cell body. The axon starts from the cell body, dividing into smaller branches and then ends at the nerve terminals. The dendrites also branch from the cell body, receiving information from the other neurons. Axons from other neurons forms

The nervous system is one of the most important organ systems in the body. It is in charge of all of the things that happen within the body. Being responsible for receiving sensory input from internal and external stimuli, integrating and processing information, and generating output, it would be hard to survive without a nervous system; however, there are different types of nervous systems in various organisms. Humans, cnidarians, flatworms, and annelids all have very diverse nervous systems. There are similarities and differences in each of these beings.

Multiple Sclerosis, also known as MS, is a disease involving progressive myelin degeneration, which results in loss of muscle strength and coordination. MS is a potentially disabling disease of the central nervous system, in which the immune system attacks the myelin that covers the

It is an autoimmune condition. It is also inherited and also can be associated with medical conditions.

Neurons (also known as neurons, nerve cells and nerve fibers) are electrically excitable and the most important cells in the nervous system that functions to process and transmit information. Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons.

The nervous system (NS)consists of the central nervous system (CNS) and peripheral nervous (PNS.) It is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The NS integrate all physical, emotional, and intellectual activities. These two structures

If one loses heart and stops lifting weights, their muscles will become weaker and smaller.

As such, neurons form the basic and functional units of the nervous system. The big picture behind the work of the nervous system and its neurons is that a change in the environment (Stimulus) causes us to produce some response to that change. Just as electricity travels in a wire, rapid impulses travel through neurons to relay messages. These are because of the charged particles, known as ions, that create either resting or action potentials in our bodies, using the sodium-potassium pump. The stimulus, however, is first detected by a receptor, such as our eyes or ears and is then coordinated with an effector, such as muscle contraction, that produces an effect, in response to the stimulus. Impulses caused by stimuli and picked up by receptors travel through nerves that consist of one type of neuron, called sensory neurons until reaching the central nerves system, which is essentially the brain and spinal cord. In other cases, nerves may contain motor neurons, that send signals to muscles and glands in our bodies. There may also be a combination of motor neurons and sensory neurons in other nerves. This eventually ends in our bodies responding to the initial change. The anatomy of the neuron in the simplest form consists of a cell body, nucleus, dendrites, axon, myelin sheaths, axon branches and axon bulbs. The cell body of the neuron

There are two cavities of the human body I would like to share first. The Cranial cavity is part of the dorsal cavity but the cranial is inside the skull. The dorsal cavity divided in two housing the brain. Secondly, Spinal cavity formed through the spinal cord and process through the dorsal cavity. The ventral cavity is a view of the front of the human body and the thoracic cavity hold the lungs. The thoracic cavity is secured by the rib cage and muscles. The abdominal pelvic cavity holds the stomach, small and large intestines. Also, the liver, pancreas, spleen, gallbladder, and kidneys. The abdominal cavity and Pelvic cavity hold the reproduction organs and bladder. In a female, a uterus and vagina work between organs. The rectum is in the

The nervous system is a complex, sophisticated system that regulates and coordinates body activities. It is made up of two major divisions: the central nervous system (the brain and spinal cord) and the peripheral nervous system (all other neural elements). The brain sends out signals through electrical signals—called impulses—that control the muscles of the body. Unfortunately, nerve and muscle problems cause the muscles to react in abnormal ways.

When the body is in repair mode (whilst resting, usually during the night time), those micro-tears especially, it follows that the muscle should grow larger; however,

Nerve cells: Nerve cells are found in your nervous system. The function of the nerve cell is to transfer messages from one part of your body to the other. Your nervous system has millions of nerve cells, called neurons. Neurons transfer messages throughout the body. The neurons carry messages called nerve impulses. Nerve impulses are created either by the neurons getting excited, or sound and pressure.
