Name the type of joint, and list the movements permitted at the shoulder joint. Under each movement’s name, list the names of the muscles responsible for each of these movements along with descriptions of their bone insertion.

Assignment 2 Weight: 5% Minimum Pass Grade: 50% Each question is worth 10 marks. 1. Name the type of joint, and list the movements permitted at the shoulder joint. Under each movement’s name, list the names of the muscles responsible for each of these movements along with descriptions of their bone insertion. 2. What are EPSPs and IPSPs, and how are they produced? Explain how these electrical currents are used in spatial and temporal summation to initiate or inhibit the generation of an action potential. 3. Match the items in column A with the descriptions in column B to create the BEST MATCHES. Items in column A can be used only once when making matches to column B. There is only one correct answer for each blank space. Column A Column B 1. pia mater 2. denticulate ligaments 3. epidural space 4. dura mater 5. arachnoid mater 6. tract 7. nucleus 8. horn 9. nerve 10.ganglion 11.endoneurium 12.meningeal branch 13.ventral ramus 14.rami communicantes 15.dorsal ramus 16.tendon reFex 17.cranial reFex 18.spinal reFex 19.autonomic reFex 20.contralateral reFex 21.polysynaptic reFex 22.crossed extensor reFex 23.ipsilateral reFex 24.monosynaptic reFex branch of spinal nerve serving vertebrae; vertebral ligaments and blood vessels of the spinal cord a group of axons with common functions within the spinal cord (or brain) responsible for transmitting nerve impulses for sensing crude touch a group of cell bodies found outside the spinal cord (or brain) branch of spinal nerve serving anterior trunk and extremities composed of collagen and ±ne elastic ±bers; highly vascular connective tissue coverings of axons within spinal nerves coordinate movements with visual stimuli extension of the leg at the knee joint in response to tapping the patellar ligament extensions of pia mater; suspend spinal cord within vertebral canal plantar Fexion of the foot in response to tapping the calcaneal tendon responsible for transmitting nerve impulses for Assignment 2 :: Biology 235: Human Anatomy and Physiology 1

Describe how the central nervous system is protected From injury. List the components oF a spinal refex arc. Describe the Function oF each component. 5. Outline the di²erences between a special sensory, motor and mixed cranial nerve, and briefy describe the Functions oF each sensory component oF the cranial nerve. 6. Complete the Following sentences by ±lling in the blanks with the correct terms or phrases. a. The nervous system regulates involuntary actions such as muscle contraction. b. Increased by the sympathetic division oF the autonomic nervous system generally heart rate. c. The ±rst motor neuron in any autonomic motor is called a neuron. d. The division oF the autonomic nervous system is also called the craniosacral division because the cell bodies oF its neurons are located in the brain stem and region oF the spinal cord. e. Parasympathetic ±bers arise From the cranial and areas oF the CNS. F. Most sympathetic postganglionic ±bers secrete the neurotransmitter , whereas parasympathetic postganglionic ±bers secrete the neurotransmitter . g.
