Introduction Three sources of sensory information are used by the nervous system in the maintenance of equilibrium. These are the eyes‚ proprioceptive endings throughout the body and the vestibular portion of the internal ear. In the development of the human body functions‚ the vestibular system is one of the first of the sensory integrative systems to be fully functional. The complete integration of the other sensory systems like vision and proprioception are continued throughout childhood

following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior. There are 2 neurons afferent neurons these carry messages to the central nervous system. Efferent neurons carry messages from the central nervous system. Neurons communicate through voltage changes. This can sometimes lead to quick action reaction sequence of voltage alterations. An example would be when you touch something hot and you pull your hand away immediately

We have all experienced some level of physical pain in our life‚ ranging from a simple pinch to bone-breaking‚ tissue-tearing‚ excruciating pain. When we feel that sensation of pain‚ what is actually happening at the chemical level within our body? As children‚ the majority of us believe that pain happens at the epidermis level because we can see an injury or believe we feel it on our skin‚ even though it may be at a deeper level. The older we get the‚ more educated we become and learn that pain

What does the term “feedback system” refer to with respect to homeostasis? A cycle of events in which a variable‚ such as body temperature‚ is continually monitored‚ assessed‚ and adjusted. 4. List the three components of a feedback system and describe each briefly. A sensor that detects a change in

The most common explanation for GBS is the demyelination of the peripheral nervous system. Other causes in question include flu vaccinations and certain bacteria such as Campylobacter Jejuni. Patients diagnosed with GBS start off with a febrile episode‚ followed by muscle weakness‚ ascending paralyzation‚ and increased oral secretions

INTRODUCTION Pediatric nursing or child health nursing is the specialty nursing care of infants‚ children and adolescents. Pediatric nursing is an excellent career for those who love kids and don’t mind hard work. The day of a pediatric nurse can be hectic‚ working with patients that range from newborns to teenagers. No two days are ever the same. Pediatric nurses work mostly on the pediatric halls in hospitals‚ although some may also work in a doctor’s office. The work involved

to physical‚ cognitive‚ and emotional development. Building of the brain The functions of the brain and the reflexes derive from the central nervous system. The central nervous system is located in the brain and the spinal cord‚ which is a bundle of nerves running through the backbone. The nervous cord in spine then branches out into a peripheral network of nerves extending to every part of the body. The brain then sends nerve signals or commands to specific parts of the body. The brain
