Babies flinch in their sleep due to the Moro reflex, also known as the startle reflex. This reflex is an involuntary response to a sudden noise or movement, causing the baby to fling their arms out and then bring them back in. It is believed to be a primitive survival instinct that helps protect the baby from potential dangers.

Why do babies hold their breath when air's blown in their face?
Babies have a natural reflex called the "glottal closure reflex" that causes them to hold their breath when they feel a sudden burst of air on their face. This reflex helps protect their airway and prevent them from inhaling any foreign particles.
Is sweating a reflex action?
No it is not a reflex action
Why does my cat's back twitch when I pet him?
When you pet your cat and their back twitches, it is likely due to a reflex called the "scratch reflex." This is a natural response in cats that causes their muscles to twitch when stimulated, similar to how humans might flinch when touched unexpectedly. It is a normal and common reaction in cats and is not usually a cause for concern.
What is a reflex action and how is this a good test of such an action?
A reflex action is an involuntary and immediate response to a stimulus, often mediated by the spinal cord without direct involvement of the brain. A common test for such an action is the knee-jerk reflex, where tapping the patellar tendon causes the leg to kick out. This response demonstrates the efficiency of the reflex arc, highlighting the body's ability to react quickly to stimuli for protection and coordination. Such tests are useful in assessing the integrity of the nervous system.
The reflex that causes an infant to close its fist when the palm is touched is called the what reflex?
The reflex that causes an infant to close its fist when the palm is touched is called the grasp reflex.
What is a difference between reflex and voluntary action?
The difference between reflex and voluntary action is that a reflex occurs naturally in response to some sort of stimulus and voluntary action is something that is consciously carried out.

What is effector muscle for calcaneal reflex action?
The effector muscle for the calcaneal reflex (also known as the Achilles reflex) is the gastrocnemius muscle in the calf. When the Achilles tendon is tapped, it causes a contraction of the gastrocnemius muscle, resulting in plantar flexion of the foot.
Is reflex action and reflex arcs are same?
Reflexes are uncontrollable movements that happen almost instantly in response to a stimuli. A reflex arc, a neuronal circuit that controls reflexes, is where reflex activities takes place.
Is blinking a flinch?
Blinking is not typically considered a flinch, although both are reflexive responses. Blinking is a natural reflex that helps protect the eyes from irritants and maintain moisture, while a flinch is a quick reaction to fear or surprise. While both involve involuntary muscle contractions, they serve different purposes and are triggered by different stimuli.
What is a synapse in a simple reflex action?
A synapse in a simple reflex action is a junction between two neurons where signals are transmitted. In a reflex action, when a stimulus triggers a sensory neuron, it sends a signal across a synapse to a motor neuron, which then causes a rapid response from a muscle or gland.
