The two divisions of the autonomic nervous system are the parasympathetic (rest and digest) and the sympathetic (fight or flight) nervous system. 16. Atropine was administered in the ED as part of Dr. Westwood’s care. What effect did it have on his vitals after it was administered? Atropine acts as an antagonist within the central nervous system, which means it acts as a blocker of specific cellular functions.
c) How does one nerve cell communicate with another? - Nerve cells communicate with one another through neurotransmitters. 2. a) Explain what neurotransmitters are? - Neurotransmitters are chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing where that neuron will generate a neural impulse.
4. A motor neuron conducts a nerve impulse along an efferent pathway from the integration center to an effector. 5. An effector responds to the efferent impulses by contracting (if the effector is a muscle fiber) or secreting a product (if the effector is a gland). Reflexes can be categorized as either autonomic or somatic.
ch 12 review 1 what are the components of the CNS? The PNS? - CNS consists of the brain and spinal Cordially, PNS consists of all other nervous tissue 2 what is difference between afferent neurons and efferent neurons? Which one is associated with sensory neurons? With motor neurons?
Myelinated neurons are typically found in the peripheral nerves (sensory and motor neurons), while non-myelinated neurons are found in the brain and spinal cord. * Dendrites or nerve endings - These small, branch-like projections of the cell make connections to other cells and allow the neuron to talk with other cells or perceive the environment. Dendrites can be located on one or both ends of the cell. | Basic Neuron Types Neurons come in many sizes. For example, a single sensory neuron from your fingertip
Stimuli’s are what transfers to the brain. The brain is dependent on neurotransmitters to send signals for one part of the brain to another part. The neurotransmitters are let go or released by nerve cells, which is what helps in carrying out cognitive functioning. When brain cells are damaged
What happens to “information” at the synapse? Data is both enhanced and incorporated at the synaptic level. Types of Synapses Electrical Synapses 2. What is another name for electrical synapses? These are also known as gap junctions.
Looking over John Henry's MRI, Cameron notices signs of a stroke, which would explain the paralyzed arm. Foreman explains the options to John Henry. They can give him heparin to thin his blood and remove the clot, but it could hurt his lungs. Another option is brain surgery to remove the clot. The surgery will either result in his death, or a clearing of the blood clot.
Reginald Lowery September 30, 2011 General Psychology (R57-F11C) Research Assignment Alex’s Story After watching Alex’s story, I question why kids are being medicated. Nearly everyone has heard of Attention Deficit Hyperactivity Disorder (ADHD) and probably knows a child who has it. This isn’t surprising since approximately six million children, or two per every classroom, are currently taking stimulants to modify behavior. It is also likely that many have been in heated debates about ADHD and medication. Are doctors too quick to prescribe medication?
In turn, the doctor can then compare these readings against those of a normal functioning brain. One more testing procedure is a SPECT (Single Photon Emission Computer Tomography) test. A doctor injects a compound that attaches itself to the dopamine receptors in a patient’s brain. The SPECT test takes a picture of the brain and the doctor can look for abnormal functions in the brain. Another form of testing is Autonomic testing.
