Xena eventually catches Callisto (remember, she is 25 years old). Salmoneus, who is 60 years old, agrees to deliver Callisto to face charges for war crimes. On the way, their cart crashes down a ravine. Salmoneus also suffers damage to his spinal cord during the accident. Compare the likely degree of regeneration/recovery of his spinal cord with that of the injured skeletal muscles and describe the consequences of your observations for his quality of life and ability to remain active.

A typical spinal nerve: Select one: a. normally divides into four branches that will supply the thoracic region, the abdominal region, the pelvic region and the limbs b. is covered by the connective tissue called epineurium c. attaches to the spinal cord via the dorsal root ganglia d. is protected by the dura, arachnoid and pia mater e. contains one nerve fibre and it's myelin sheath

The striatum is a structure within the basal ganglia.  The striatum is comprised mostly of medium spiny neurons that express either D1 receptors or D2 receptors.  These neurons when active release the neurotransmitter _______

Steven had a stroke resulting in his having difficulty speaking. Ruth suffered a severe nerve injury to her left arm while working, but after a few weeks regained full use of her arm. Why is Steven having difficulty regaining his speaking ability; whereas, Ruth has regained full function in her arm. Base your answer on nervous system regeneration and repair.  Please respond with 1-2 paragraphs.  (Hint: Section 12.10) Even though both injuries are nervous system injuries. There is a major difference between these two injuries: Central Nervous System versus Peripheral Nervous System!

A 25-year-old soldier suffers a gunshot wound on the lower part of his back and is unable to move his legs. A neurologic examination and magnetic resonance imaging (MRI) scan reveal injury of the cauda equina. No other dysfunction is noted. Damage to the following structure could explain the inability to move his legs: dorsal primary rami at spinal cord level L2. True O False

Surgeons were able to reattach Irving’s amputated limb, sewing both the nerves and the blood vessels back together. After the surgery, which proceeded very well, the limb regained its blood supply almost immediately, but the limb remained motionless and Irving had no feeling in it for several months. Why did it take longer to reestablish innervation than circulation?

Simon was injured in a football game. In the emergency room, the emergency room physician pricked his skin, beginning at his feet, to see if there was a spinal cord injury and if so, what area was the most likely to be injured. Why did the physician prick his skin with a needle to determine the possibility of spinal cord injury?  Please respond with 1-2 paragraphs.

A Case of Spinal Cord Injury Jason is a 21 year old senior at the University of South Africa, majoring in economics. While on spring break in Johannesburg, Jason was involved in a motorcycle accident. In the accident he was thrown from his pike to the pavement, landing on his back. A police officer witnessed the accident and immediately called for medical assistance. Emergency personnel arrived within minutes, and upon recognizing the seriousness of Jason's back injury, immobilized his neck and secured him to a rigid board prior to transporting him to the emergency room of the nearest hospital. When he arrived at the hospital, Jason was conscious and complained of pain in his lower back. Upon examination by the emergency room personnel, Jason was found to have numerous abrasions and contusions, and loss of both sensation and motor control of his legs. After he was stabilized, a complete neurological exam was performed to assess and localize Jason's injury. The neurological exam…
