Lab Activities

A list of words is provided below that you are expected to identify, learn, and label on the models provided. Note that not all models will have some of the organs/structures, so be sure to find them on an alternate model. You must use all the words provided. Using the colored tape provided, write the number that corresponds to the organ/structure and place them on your model. When complete, notify your TA so they may check your work.

For each additional station, directions will be provided for the activity.

Cervical plexus

Note: When labeling the nerves that exit the cervical plexus, focus on their location, the connections between the nerves of the plexus, and what they innervate. Also note any interesting characteristics you find, for example, which is the longest nerve? Make use of your textbook and atlas during this time.

#37 inferior root of Ansa cervicalis nerve

#39 segmental branches

 

Station Three: Brachial Plexus

Label the models of this station with the number that corresponds to the appropriate structure of the peripheral nervous system using the colored tape. When you are finished, ask your TA to check your labeling. Before leaving the station, remove all the labels you have placed on the model.

Note: When labeling the nerves that exit the brachial plexus, focus on their location, the connections between the nerves of the plexus and what they innervate. Also note any interesting characteristics you find, for example, which is the longest nerve? Make use of your textbook and atlas during this time.
