Case Study : Wearing On Her Nerves

The nervous system is one of the body’s complex functions that contain a network of cells and nerves that transmit signals from the brain and spinal cord to different areas of the body. It is categorized into two groups; the central nervous system which is made up of the brain and spinal cord, and the peripheral nervous system which contains the body’s nervous tissue and is where neurologic responses occur. Homeostasis, which is the process in which thermoregulation is maintained, also happens in this area.

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.

The areas of Michael's brain that were injured during his birth affected his control over his voluntary movements. Which part of the nervous system distributes motor commands to skeletal muscles?

The somatosensory system has to do with touch, pressure, pain, temperature, movement, and vibrations from muscles, joints, and skin. Uit sends sensations through the spinal cord, to the brainstem, then the thalamic relay nuclei to the parietal lobe that houses the sensory cortex.

In the organization of the Human Nervous System it is divided into sections such as the sensory system, which gathers and process information from the surrounding environment: motor systems which responds from environment by sending signals and information to facilitate movement behavioral responses and the associational system which is a meditator from most multifaceted and least problematic brain functions. Within these different functions of the nervous system it is divided into two components where these functions can happen the central nervous system that comprises of brain and spinal cord and peripheral nervous system that embodies nerves and ganglia.

The central nervous system consists of the brain and spinal cord. The brain takes information from the senses and processes it and it also makes decision sand sends commands to the body. The spinal cord carries information to and from away the brain. The peripheral system, on the other hand, is the system that allows communication between the central nervous system with the sensory systems. It also makes it possible for the brain and spinal cord to control muscles and

The nervous system is a multiplexed body system that controls most other body systems directly or indirectly by sending and receiving signals through a complex system of nerves. As a whole, the nervous system can be broken down into the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord while the PNS is composed of peripheral nerves that branch off of the spinal cord and continue to branch to reach the most distal points of the limbs. The PNS can be further broken down into the afferent and efferent division. The afferent division deals with information brought to the CNS from the nerve receptors. Furthermore, the afferent division breaks down into somatic sensory receptors whose

The nervous system is responsible for muscle movement. The nervous system consists of central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is constitute of the brain and the spinal cord, and PNS is a network of nerves that runs throughout the body. The brain sends electrical signals to the CNS, and they are disbursed the PNS to produce body movement (Acrobatiq, 2014). Then, these signals travel back from the PNS to CNS to coordinate the next course of action of the body (Acrobatiq, 2014). The motor cortex section in the cerebrum sends messages to the muscles to coordinate accurate movement. Also, its control balance posture during the exercise and movement. The muscles instructed by the impulses from the cerebrum move in the given direction. They relax and contract according to the message relayed by the motor neurons.

1.What are the 2 main divisions of the nervous system and the basic structures that make

The world is full of numerous resources to conduct research on just about anything one could image. Usually no two sources contain the exact same information. I used four sources to research the gluteus medius muscle. Below I will state what I found in common with each of the sources about the gluteus medius, and what I found different between the sources regarding the gluteus medius.

Carry messages from special receptors in the skin, muscles, and other internal and external sense organs to the spinal cord, which sends them to the brain

There are two main divisions that comprise the nervous system: the central nervous system consisting of the brain and the spinal cord and the peripheral nervous system consisting of somatic and autonomic nervous systems (Kalat, 2013). The brain and the spinal cord make up the central nervous system and is responsible for the transmission of nervous impulses as well as receiving sensory information (Siegal, 1999). The peripheral nervous system, consisting of cranial nerves, spinal nerves, and peripheral ganglia, is responsible for transmitting information to the central nervous system as well as the rest of the body (Hubbard, 2013).

The CNS contains the brain and spinal cord. Its main functions include: processing, integrating, and coordinating sensory information and motor instructions. The sensory data conducts information that is being processed from internal and external conditions the body is experiencing. Motor commands regulate and control peripheral organs (skeletal muscles). The brain functions under memory, emotions, learning, and intelligence. The PNS consist of the neural tissue found outside of the CNS. It functions in sending data to the CNS which motor commands are than carried out to the peripheral tissues/systems. Multiple nerve fibers send sensory data and motor commands in the PNS. The nerves that assist with transmitting data include the cranial nerves and spinal nerve. However, the PNS can be divided into afferent (to bring in) and efferent (to bring out) divisions of transferring data. The afferent division functions in bringing in sensory data to the CNS. Sensory structures are receptors that detect internal/external environmental change and adjusting accordingly. The efferent division functions in carrying out motor commands from the CNS to glands, muscles, and adipose tissue. The efferent division contains somatic

Another way that the nervous system can be perceived, is through motor unit recruitment. The measurement of how much motor unit recruitment that there is, it will then determine the contraction of a muscle. When a motor recruitment has less of a recruitment it will then cause a for a frailer muscle contraction. However, it is the same way if a motor recruitment has a bigger recruitment then it will have a better contraction a muscle, which is the third hypothesis. An example of motor unit recruitment is the heart, the muscle that is on the heart is the cardiac muscle, and it will have higher motor unit recruitment so that blood can circulate throughout the body.

The peripheral nervous system (PNS) is connected directly to the central nervous system, and consists of neurons and nerves that send information back and forth the CNS. Furthermore, the peripheral nervous system can be divided into two sections, the sensory nervous system and the motor nervous system. The Sensory The sensory nervous system is in charge of transmitting data from a variety of internal organs or from external stimuli to the central nervous system using sensory nervous cells. On the other hand, the cells of the motor nervous system (motor neurons), take the impulse from the CNS to effectors, which include glands and muscles. In addition, the motor nervous system can be further divided into the somatic nervous system, controls voluntary actions of the skeletal muscle and external sensory organs, whilst the autonomic nervous system operates
