The vomiting reflex is mediated by the?
Vomiting reflex is mediated by the vomiting center in the brainstem, specifically the area postrema. This area receives input from various parts of the body, including the gastrointestinal tract and higher brain centers, to initiate the coordinated response of vomiting.
What type of reflex has the control center in the brain stem?
Reflexes that have their control center in the brain stem are known as brain stem reflexes. These include vital reflexes such as the gag reflex, cough reflex, and pupillary reflex, which are essential for survival and basic bodily functions. The brain stem integrates sensory inputs and coordinates motor responses, allowing for immediate reactions to stimuli. These reflexes are typically involuntary and occur without conscious thought.
How can you remember the stages of a reflex arc in chemistry?
To remember the stages of a reflex arc in chemistry, you can use the acronym "SAID" which stands for stimulus, afferent pathway, integration center, and efferent pathway, and then the response. This mnemonic can help you recall the order of events in a reflex arc.
Vomiting reflex is mediated by the?
Chemoreceptor trigger zone (CTZ) in the medulla of the brainstem, which communicates with the vomiting center (to mediate the vomiting reflex).
Which part of the reflex arc changes body condition levels?
The control center of a reflex arc, typically located in the central nervous system, processes incoming sensory information and initiates a response to change body condition levels.
What Acts as a reflex center of the body?
the spinal cord
What is the primary reflex center for the body?
The primary reflex center for the body is the spinal cord. It coordinates reflex actions in response to stimuli without involving the brain, allowing for quick and automatic responses to potential threats or dangers.
What is the control center of micturation reflex?
central.somatic and autonomic nervous systems
What is the main reflex center of the central nervous system?
spinal cord
What are the five parts of a reflex?
Five parts of a reflex arc are the receptor, sensory neuron (afferent), integration center, motor neuron (efferent), and effector.
What is the pathway between the receptor and the control center in the reflex pathway?
Afferent pathway
The vomiting reflex is mediated by the?
Vomiting reflex is mediated by the vomiting center in the brainstem, specifically the area postrema. This area receives input from various parts of the body, including the gastrointestinal tract and higher brain centers, to initiate the coordinated response of vomiting.
Is the micturition reflex center is located in the pons?
No, the micturition reflex center is located in the sacral region of the spinal cord, specifically at the level of the S2 to S4 segments. This center regulates the process of urination, including the contraction of the bladder and relaxation of the internal urethral sphincter.
What type of reflex has the control center in the brain stem?
Reflexes that have their control center in the brain stem are known as brain stem reflexes. These include vital reflexes such as the gag reflex, cough reflex, and pupillary reflex, which are essential for survival and basic bodily functions. The brain stem integrates sensory inputs and coordinates motor responses, allowing for immediate reactions to stimuli. These reflexes are typically involuntary and occur without conscious thought.
Does visceral reflex arcs have two sensory neurons?
No, it has 2 visceral motor neurons. A visceral reflex has a receptor, a sensory neuron, a processing center, and 2 visceral motor neurons.
The micturition reflex center is located in the?
sacral segments of the spinal cord
What is the pathway between the receptor and the control center in the reflex pathway called?
Afferent pathway
