together with some new results. Efforts to determine neck injury mechanisms was based on a hypothesis stating that injuries to the nerve root region in the cervical spine are a result of transient pressure gradients in the spinal canal during rapid neck bending. In experimental neck trauma research on animals‚ pressure gradients were observed and indications of nerve cell membrane dysfunction were found in the cervical spinal ganglia. The experiments covered neck extension‚ flexion and lateral bending

Sensation: Intro Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception is the process of organizing and interpreting sensory information enabling us to recognize meaningful objects and events. Bottom-up processing is the analysis that begins with the sense receptors and works up to the brain’s integration of sensory information. Top-down processing is information processing guided by higher-level

movements and jumps (Merriam-Webster Dictionary). For figure skaters‚ however‚ the ice-ring is their second home and skating is their freedom‚ remedy‚ and life. For them‚ figure skating is not only about jumps and various movements; it is about handling nerves and controlling pressure. A skater needs to have good balance on the ice in order to remain stable. This is due to the understanding of the center of mass‚ which is the point of balance where all the mass of the object is concentrated. As the figure

Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport without requiring bulk motion. Thus‚ diffusion should not be confused with convection or advection‚ which are other transport mechanisms that use bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach starting

when the roots of the sciatic nerve are cut * As we cut the root of the right sciatic nerve of the frog in the experiment‚ the right lower leg of the frog becomes limp. The right gastrocnemius muscle lost its firmness and becomes flabby while I have observed as we compared the tonicity of the muscles with the left gastrocnemius muscle (with the root of left sciatic nerve is still intact) it is different. The left gastrocnemius muscle remains firm with the sciatic nerve connected. This observation

The increase in calcium leads to: increased force of contractions‚ increased cardiac output and renal perfusion‚ slower heart rate‚ and decreased conduction velocity through the AV node (Karch‚ 2017).
