This is an ungraded pratice assignment for the test, i'm having trouble tracing A,B,C,D. There are examples provided 1. General Motor Tract: Review the corticospinal tract presented in the text. Study the basic format and the example provided below. This tract is the same for all of the motor tracings you are responsible for. Variations only occur at the appropriate ramus, appropriate plexus, appropriate spinal nerve, and appropriate skeletal muscle FORMAT: Motor Cortex of cerebrum -> Internal Capsule -> Mesencephalon -> Pon -> Medulla -> Anterior Horn (synapse) -> Anterior Root -> Exit appropriate ramus -> Appropriate plexus -> Appropriate Spinal Nerve (s) -> Muscle (synapse 2. General Sensation Tracts: Review the general sensory tract presented in the text. Study the basic format and the example provided below. This tract is the same for all of the sensory tracings you are responsible for. Variations only occur at the appropriate receptor, appropriate spinal nerve, appropriate plexus, and appropriate ramus. FORMAT: Specific receptor Appropriate spinal nerve (s) ->Appropriate plexus (if needed) -> Enters appropriate ramus -> Dorsal Root Ganglion -> Dorsal Root -> Dorsal Horn (Synapse) ->Thalamus (Synapse) -> Internal Capsule -> Appropriate Sensory Cortex (Cerebrum) 3. Sensory and Motor Tracings: Review the sensory and motor tracings presented and complete the following tracings. Remember that specific receptors (chemoreceptors, proprioceptors, nociceptors, thermometers, photoreceptors, mechanoreceptors.), effectors, nerves, plexuses, or rami will vary depending on the specific example studied a) You step barefoot on hot sand. Trace the sensory message of pain from the receptor on the bottom of your foot to the appropriate sensory cortex. Include the specific nerves b) Your friend is massaging your back with deep pressure. Trace the sensory message of pressure from the receptor on your back to the appropriate sensory cortex c) While hanging a picture on the wall the hammer slips and you hit your thumb. You experience a great deal of pain. 1) Using the general sensation tract, trace the sensory pathway from the appropriate receptor to the brain. Include the specific nerves. 2) Now trace the motor pathway from the brain to the wrist extensors to move your thumb away from the hammer. d) In order to perform bicep curls you must flex the anterior flexor muscles of your arm. Trace the motor pathway from the brain to the appropriate muscles.

Question

This is an ungraded pratice assignment for the test, i'm having trouble tracing A,B,C,D. There are examples provided

1. General Motor Tract: Review the corticospinal tract presented in the text. Study the basic format and the
example provided below. This tract is the same for all of the motor tracings you are responsible for. Variations only
occur at the appropriate ramus, appropriate plexus, appropriate spinal nerve, and appropriate skeletal muscle

FORMAT:
Motor Cortex of cerebrum -> Internal Capsule -> Mesencephalon -> Pon -> Medulla -> Anterior Horn (synapse) -> Anterior Root -> Exit appropriate ramus -> Appropriate plexus -> Appropriate Spinal Nerve (s) -> Muscle (synapse

2. General Sensation Tracts: Review the general sensory tract presented in the text. Study the basic format and the
example provided below. This tract is the same for all of the sensory tracings you are responsible for. Variations
only occur at the appropriate receptor, appropriate spinal nerve, appropriate plexus, and appropriate ramus.

FORMAT:
Specific receptor
Appropriate spinal nerve (s) ->Appropriate plexus (if needed) -> Enters appropriate ramus -> Dorsal Root Ganglion -> Dorsal Root -> Dorsal Horn (Synapse) ->Thalamus (Synapse) -> Internal Capsule -> Appropriate Sensory Cortex (Cerebrum)

3. Sensory and Motor Tracings: Review the sensory and motor tracings presented and complete the following
tracings. Remember that specific receptors (chemoreceptors, proprioceptors, nociceptors, thermometers,
photoreceptors, mechanoreceptors.), effectors, nerves, plexuses, or rami will vary depending on the specific example
studied

a) You step barefoot on hot sand. Trace the sensory message of pain from the receptor on the bottom of your foot to
the appropriate sensory cortex. Include the specific nerves

b) Your friend is massaging your back with deep pressure. Trace the sensory message of pressure from the receptor
on your back to the appropriate sensory cortex

c) While hanging a picture on the wall the hammer slips and you hit your thumb. You experience a great deal of
pain.

1) Using the general sensation tract, trace the sensory pathway from the appropriate receptor to the brain.
Include the specific nerves.
2) Now trace the motor pathway from the brain to the wrist extensors to move your thumb away from the
hammer.

d) In order to perform bicep curls you must flex the anterior flexor muscles of your arm. Trace the motor pathway
from the brain to the appropriate muscles.
