The dissection of the foot is reasonably straight forward if you keep in mind the distinction between extrinsic and intrinsic muscles and the axis through the mi. It is helpful to approach the dissection in layers.

Basic concepts:
You may wish to review the basic concepts for the lower limb at this time. The link opens a new window which you will need to close to return to this page.

Specific Learning Objectives:

1. Define the venous drainage (both superficial and deep).
2. Recall the cutaneous innervation of the foot. Compare and contrast a dermatome and the cutaneous innervation of specific nerves.
3. Summarize the functions of muscles in each of the compartments. Knowing the functions helps you learn the attachments (origins and insertions) of individual muscles?
4. Recall which spinal segments contribute to each peripheral nerve.
5. Describe the innervation of each compartment and the specific deficits that occur with lesions of individual nerves at different parts along the course of each nerve. Where can the above nerves be checked for sensory loss?
6. Describe the vascular pattern and major arteries and the major anastomoses in the foot.
7. Compare and contrast intrinsic and extrinsic muscles of the foot.
8. Identify anatomic structures in radiographic studies including X-ray, CT scans and MRI films.

Difficult parts of the dissection:

1. While this dissection is not difficult conceptually, it does take patience so give your self time.
