The reflex involved when you stroke an infant's cheek and she/he turns toward the stimulator and begins to suck is called the rooting reflex.
The rooting reflex is one of the baby’s involuntary movements that help them find breast or a bottle to begin feeding. It occurs when the baby’s mouth touches the skin and as a consequence turn their heads. This reflex is typical for the first few months of baby’s life.
The neuromuscular synapse is a chemical synapse between a motoneuron and a muscle cell (muscle fiber). The neuromuscular synapses consist of:
• the pre-synaptic cell-motoneuron that sends signal by releasing the the neurotransmitter from the synaptic vesicles
• synaptic cleft, place where neurotransmitter is released, between motoneuron and muscle fuber
• post-synaptic cell also called endplate -the muscle cell that receives the signal via receptors.
