Nervous System Divisions
Sympathetic and Parasympathetic Nervous System
Somatic Neuron's are responsible for what type of control?
Voluntary
Which nervous system of the ANS is responsible for the rest and digest response?
Parasympathetic Nervous System
Neurons that release acetylcholine are known by this term?
Cholinergic
This cranial nerve is responsible for hearing and balance?
Vestibulocochlear nerve (CN VIII)
The Spinal cord is categorised as a component of which nervous system?
Central nervous system
A single motor neuron extending from the CNS directly to an effector organ describes the motor pathway of which division of the nervous system?
Somatic Nervous System
This division of ANS has long preganglionic and short postganglionic neurons.
Parasympathetic Nervous System
These cholinergic receptors mediate fast, immediate, and always excitatory responses.
Nicotinic receptors
What Nerve is the only nerve that is innervated by the CNS?
Optic Nerve (CN II)
The Peripheral Nervous System has how many pairs of spinal nerves?
31 pairs of spinal nerves
The autonomic nervous system innervates these three types of effector organs.
Cardiac muscles, smooth muscles and glands
Ganglia located close to the vertebral column are characteristic of which division of the autonomic nervous system?
Sympathetic Nervous System
The 2 types of neurotransmitters released at the post-ganglionic axon terminal of the Sympathetic Nervous System is?
Epinephrine and Norepinpehrine
This cranial nerve carries the largest amount of sensory information from the face while also innervating the muscles of mastication.
Trigeminal nerve (CN V)
Touching a hot stove activates receptors in the skin. Before you consciously perceive the pain, information first travels through this division.
Peripheral Nervous System
All Pre-ganglionic Neurons of the Autonomic Nervous System release what kind of neurotransmitter?
Acetylcholine
Preganglionic neurons originating from the craniosacral region are characteristic of this division of the autonomic nervous system.
Parasympathetic Nervous System
What are the two types of cholinergic receptors?
Nicotinic and Muscarinic receptors.
Which cranial nerve would you test by asking a patient to shrug their shoulders against resistance?
Accessory nerve (CN XI)
A patient can voluntarily move their limbs but cannot regulate blood pressure when standing. Which division is most likely impaired?
Autonomic Nervous System
Which neurons of the peripheral nervous system are unmyelinated?
Postganglionic autonomic neurons
During a marathon, one branch increases cardiac output while simultaneously decreasing gastrointestinal activity. Which branch is responsible?
Sympathetic Nervous System
Norepinephrine binds to β2 receptors on which organ
Lungs
Name the four Cranial nerves that carry signals to the parasympathetic nervous system.
Oculomotor nerve (CN III), Facial nerve (CN VII), Glossopharyngeal Nerve (CN IX), and Vagus nerve (CN X)
