stimulus is called a reflex. This action is controlled by the human nervous system and is considered an involuntary response – it happens without our even having to think about it. On the other hand‚ voluntary responses occur when we have to think to react. It is possible to stop a reflex reaction‚ but it would take a lot of voluntary control. A good example of a reflex is the “knee-jerk” response the doctor tests during a physical examination. In a healthy person‚ this stretch reflex maintains posture

Describe mammalian hibernation‚ making sure to include specifics on body temperature drops‚ metabolic rates‚ and respiratory rates. Mammalian hibernation is a process the body undergoes when trying to protect against extreme weathers and to help conserve energy for a few weeks or an extended period of time while a food source is scarce. Hibernation is a state where metabolic rate is low or

reflexes that babies are born with are root reflex‚ suck reflex‚ moro reflex and grasping reflex and each of them has a function in infants. • Root Reflex This reflex begins when an infant’s cheek is rubbed or the side of the mouth is touched. In response‚ the baby turns his or her head and open his or her mouth to follow and root in the direction of the stroking. Also‚ the infant begins to make sucking movements with his or her mouth. Therefore‚ this reflex plays an important role as it is the most

and Moro reflexes and most if not all new-borns have them. Rooting reflex is when you touch the baby’s cheek and their head will move in that direction‚ their mouths opened wide‚ this ensures successful breast feasting. They do this‚ hungry or not as a reflex. The rooting reflex is strong for the first 3-4 months‚ but normally disappears by their first birthday. The grasping reflex‚ sometimes called the palmers grasping reflex‚ is when your baby with grasp onto your finger‚ hair and jewellery for

Introduction: There are three theories of motor development maturation‚ information processing and the dynamic theory. The maturation theory focuses on the neurological factors that affect the development of motor skills‚ and is the term used to describe the innate sequences of physical changes (Macintyre and McVitty‚ 2004‚ pp 57). Whereas the information processing theory focuses on belief that thinking is information processing through senses (Cech and Martin 2005) Within this theory it talks

The goal of this lab is to help understand a reflex arc‚ study the time taken between a stimulus and a response‚ how the spinal cord and peripheral nerves function‚ and how to measure and record response time related to a stimulus using the Labscribe software. For the second part of the lab‚ electromyograms will be triggered and recorded in order to study the Achilles and patellar stretch reflex and the reflex arc. Also‚ to understand nerve conduction velocity‚ EMG‚ and motor

The purpose of this lab is focus towards testing our reflexes and sensory physiology. We use these every day but we rarely do understand how much they contribute to our ability to function normally. A reflex is a rapid‚ involuntary motor response to stimuli. We will be conducting several
