Spinal Cord, Spinal Nerves, and ANS Lab HW 220

Intro to Neuroscience   Q: Which of the following statements ACCURATELY describe spinal cord organization. α-motor neurons are organized from lateral to media such that those found towards the medial section of the spinal cord controls the distal muscles. Lumbar spinal cord enlargement is observed where neurons that innervate the legs and feet are located Neuronal cell bodies (somas) of neurons that innervate single muscles are only found in a single spinal cord segment. Muscles of the trunk are represented medially while muscles of arms and hands are represented laterally Group of answer choices 1, 2, 4 2, 3, 4 2, 4 4 only 1,2,3,4     Question: Both upper and lower motor neurons are involved in controlling the activity of your right bicep. Where do the cell bodies of these motor neurons live? Group of answer choices Upper motor neuron – left motor cortex; lower motor neuron – left spinal cord Upper motor neuron – left motor cortex; lower motor neuron – right spinal…

Anatomy of the Spinal Cord 1. Complete the following statements by inserting the proper anatomical terms in the answer blanks. The superior boundary of the spinal cord is at the level of the foramen magnum of the skull, and its inferior boundary is at the level of vertebra. The collection of spinal nerves traveling in the vertebral canal below the terminus of the spinal cord is called the 3. The spinal cord is enlarged in two regions, the and the regions. What is the significance of these enlargements?

Intro to Neuro Question: Huntington’s disease causes too much ballistic movement due to which of the following reasons? Group of answer choices Loss of the inhibitory connection between the striatum and the globus pallidus external Loss of the inhibitory connection between the striatum and the globus pallidus internal Loss of the inhibitory connection between the globus pallidus external and the globus pallidus internal Increased activity of globus pallidus internal neurons   Is my reasoning correct? Huntington's disease is characterized by the degeneration of neurons in the striatum, particularly those that project to the globus pallidus external (GPe) in the indirect pathway. The correct reason for too much ballistic movement in Huntington's disease is: Loss of the inhibitory connection between the striatum and the globus pallidus external. This loss weakens the indirect pathway, reducing its ability to suppress unwanted movements, leading to the hyperkinetic symptoms…

Name: The Neuron 1. Processes that carry the action potential (impulse) away from the cell body are called 2. The short, numerous, receptive processes of a neuron are called 3. Gaps in the myelin sheath are called the 4. The CNS consists of the and 5. The PNS consists of the nerves and nerves. 6. Neurons that carry an impulse from a sensory receptor to the CNS are called neurons. 7. Neurons that carry an impulse from the CNS to a muscle or gland are called neurons. 8. Regions of the brain and spinal cord that contain myelinated fibers are referred to as matter. Areas with unmyelinated cell bodies are referred to as matter. 9. Label each of the indicated structures on the neuron below: This neuron is representative of the type of known as a neuron.

Subject: Anatomy and PhysiologyReflexes are often used for diagnosing disorders of the nervous system and locating injured tissues in the body. Describe 2 somatic reflexes and explain the reason why these reflexes can cease to function or function abnormally. Use 4-7 sentences for each. Separate your answer in paragraphs.

Part A - Identification of Spinal Cord Structures All information related to somatosensation (nociception, thermosensation, pruriception (itch), mechanosensation, and proprioception) is processed and directed to the brain in the dorsal spinal cord. The motor neurons of the ventral horns control the voluntary skeletal muscles. Study the structures of the spinal cord and then match the structure with its correct location. 00 1 5 6 7 8 9 10 2 11 3 12 4 View Available Hint(s)

Choose a cranial or spinal nerve and talk about the followings: name and number; sensory, motor or both; where does the nerve originate from in the brain or spinal cord.

Choose the correct answer to fill in the blanks: The dorsal roots carry (sensory, motor, or both) information (into, away, or both) the spinal cord. Damage to a dorsal roof is most likely to cause (parenthesis, or paralysis) in the affected area. The ventral roots carry (sensory, motor, or both) information (into, away, or both) the spinal cord. Damage to a ventral roof is most likely to cause (paresthesias or paralysis) in the affected area.

Cranial Nerve Tests The following tests are designed to help identify the functioning of the twelve pairs of cranial nerves on a patient or “test subject”. Review the following cranial nerve tests. study the case scenarios to determine which cranial nerve (there may be more than 1 for some) may be damaged in each scenario based on the results of cranial nerve tests “you” (as a pretending physician) have performed on some patients. Note that “CN” stands for “cranial nerve”. Use the images attached to help.   Case Scenario #1 You are a neurologist seeing a patient who is having trouble with her hearing. You perform a cranial nerve test by having her try to identify an object by its sound. Behind your back you jingle a bell, clap your hands, snap your fingers. The patient indicated that she heard the jingling of the bell, but not the other two sounds. You perform another test where you have the patient walk along a line on the floor. The patient walks in a zig-zag type pattern. What nerve…

Intro to Neuroscience College Describe the papez circuit at the college level of an introduction to neuroscience course. Please provide some visualizations and diagrams to go along with your explanation. So, please only include the circuit loop and not any pictures of the brain. So, draw the circuit that Papez drew in his book or lectures and that would help me understand how things get started in the hypothalamus and so on.
