Peripheral venous catheter

Neurological Factors Affecting Movement Voluntary human movement is regulated and controlled by complex interactions within our central and peripheral nervous systems. The three major types of sensory input come from the visual (eyes), vestibular (inner ear), and somatic (body) sensory systems. The somatic sensory receptors found in muscles, tendons, ligaments, joint capsules, and skin are collectively known as proprioceptors and they gather information about body position and the direction and…

body or be able to sense when things are dangerous. The nervous system is composed of primarily two parts: the central nervous system and the peripheral nervous system. The central nervous system is comprised of the brain and the spinal cord. The peripheral nervous system is made up of everything else like the cranial nerves and the spinal nerves. The peripheral nervous system connects the central nervous system…

and synaptic transmission, respectively. Neurons can be grouped together to form nerves, which are the primary organizational structures in one major branch of the nervous system, the peripheral nervous system. This is in contrast to the central nervous system, which consists of the brain and spinal cord. The peripheral nervous system can be sub divided into the somatic and autonomic nervous systems, the latter of which can be further sub divided into the sympathetic and parasympathetic nervous…

Biological psychology is a discipline, it makes very important contribution to the nervous system. I will be briefly going over biological bases of behavior and the mental processes. The first thing I will be talking about is endorphins. The second thing I will be talking about is the sympathetic nervous system, and the parasympathetic nervous system. The first thing I’m going to talk about is endorphins. Endorphins are produced by the central nervous system. Endorphins act like a morphine, or…

One of the major channels of the spinal cord is the spinothalamic tract; a sensory pathway. It conveys nerve impulses for sensing pain, warmth, coolness, itching, tickling, deep pressure, and crude touch. (Tortora, 2014-01-22, p. 461). Based on that description and as the name implies, information will travel from the region of stimulation on the skin to the CNS, ultimately landing at its destination at the thalamus; thus, making it an ascending pathway. This pathway is further divided into…

Nervous System is divided into two major sections, the Central Nervous System (CNS) and the Peripheral System (PNS). The CNS contains everybody's brain and spinal cord; this is where our body receives sensory information, generates thoughts and emotions, and stores our memories at. Our PNS contains our nerves and axons; this section is responsible to give and take information to and from the CNS. Our Peripheral System is then broken into two more sections called the Somatic Nervous System (SNS)…

artery has few if any intraneural branches, which may anastomose with the pial system to help supply the laminar region (cite). Within the central portion of the optic nerve, the central retinal artery courses adjacent to the central retinal vein. Venous drainage of the optic nerve is almost exclusively via the central retinal vein directly or indirectly. Any issues with supply or drainage of these vessels can damage the optic nerve and overall…

I chose the topic MRIs. I will discuss the following topics, what an MRI is, what is an MRI used for, and How should you prepare for an MRI and the risks and benefits. Magnetic resonance imaging (MRI) is an examination that uses a magnetic field and three dimensional detailed anatomical images to take pictures of the inside of the body. In many cases, MRI gives different information about structures in the body that can be seen with an ultrasound, X-ray, or even a computed tomography scan or as…

CVC General Consideration INDICATIONS To give medications to the patient e.g. vasopressors, chemotherapy, antibiotics1 Parentral nutrition (PEN) Hemodynamic monitoring – e.g. central venous pressure (CVP) In case of difficult or poor peripheral venous access CONTRAINDICATION: some of the relative contraindications are Anatomic distortion at insertion site Coagulopathy Already existing intravascular devices SITES Internal juglar vein (IJV) Suvclavian vein ( SCV) Femoral vein…

Even though complications of fistula access are far less than a graft or a catheter, they do occur and need to be addressed. Complications occur in approximately one-third of fistulas and include: aneurysms, infection, stenosis, thrombosis, steal syndrome and heart failure. These complications have historically been classified as early and late failure. The etiology of both early and late are somewhat similar because if the cause is not diagnosed early on it may progress and lead to late access…
