1. The soft palate (including the uvula) raises, preventing food from entering the nasal cavity.
2. The hyoid bone and the larynx are elevated. A flaplike structure attached to the larynx, called the epiglottis, closes off the top of the larynx so that food is less likely to enter the trachea.
3. The tongue is pressed against the soft palate, sealing off the oral cavity
4. The longitudinal muscles in the pharyngeal wall contract, pulling the pharynx upward toward the food.
5. Muscles in the lower portion of the pharynx relax, opening the esophagus.
6. A peristaltic wave begins in the pharyngeal muscles and forces the food into the esophagus

A Reflex Arc is a neural pathway for reflexes that is involved in CNS and PNS. The five elements are: 1. Sensory receptor (Reacts to stimuli) 2. Sensory or Afferent neuron (takes information to the CNS) 3. Integration Center (Spinal Cord or Brain processes information) 4. Motor or Efferent neuron (carries signal away from CNS) 5. Effector organ (muscles or glands)
near the equator .e.g. africa... hope this helps :)
receptor: initiate impulse: receive something sensory neuron: will carry impulse from receptors to the central nervous system motor neuron: tranmits impulse away from central nervous system into effector internuncial neuron: carry impulse from pre- synaptic to post synaptic effector: muscles or glands
You can use a flowchart or a timeline to display information in a chronological sequence of actions or definite steps. Flowcharts help illustrate a process or workflow, while timelines show events in the order they occurred over time. Both tools are visual aids that can make complex information easier to understand.
