What neurons control the heart?
The neurons responsible for controlling the heart are located in the cardiovascular center of the medulla oblongata in the brainstem. These neurons regulate heart rate and strength of contractions by sending signals through the autonomic nervous system. Sympathetic neurons increase heart rate and contractility, while parasympathetic neurons slow down heart rate.
What does the dorsal root ganglia consist mainly of?
cell bodies of unipolar neurons
Can atomic neurons be sensory or afferent neurons?
I believe you mean autonomic neurons (part of the ANS) and yes, they can be sensory neurons. Sensory neurons are the same as afferent neurons--meaning they carry signals towards the CNS. Think as afferent as 'approaching'. Anyhow, these neurons sense the conditions of your visceral organs and whatnot. Other wise it would have no information to judge for what signals to send. So yes, autonomic neurons consist of both sensory (afferent) and motor (efferent) neurons.
Does the heart consist of five chambers?
no. the heart only has 4 chambers
Does the heart consist of cardiac muscle?
yes
Heart rate is controlled by neurons of the cardiovascular center located in the?
medulla
In the spinal cord, there is a butterfly shaped structure. What does the ventral horn of this structure primarily consist of?
is: the cell bodies of motor neurons
The cells in your body are continuously disassembled and reassembled what kind of body cells last the longest?
The cells in your body that tend to last the longest are typically neurons and heart muscle cells. Neurons can last your entire lifetime, while heart muscle cells have a relatively long lifespan and are not replaced frequently.
What consist of circulatory sytem?
Heart and your arteries(veins, capillaries)
What is the name given to reflexes that involve more than 2 neurons?
The name given to reflexes that involve more than 2 neurons is polysynaptic reflexes. These reflex arcs consist of multiple interneurons between the sensory and motor neurons, allowing for more complex and coordinated responses.
What is the scientific term for heart cavities?
The 4 chambers of the heart consist of 2 atria and 2 ventricles.
What is the difference between somatic sensory neurons and visceral sensory neurons?
Somatic sensory neurons detect stimuli from the skin, muscles, and joints. Visceral sensory neurons detect stimuli from internal organs such as the heart, lungs, and intestines. Both types of neurons transmit sensory information to the central nervous system for processing.
