A survey of essential anatomy from the perspective of anesthesiology, emergency medicine, obstetrics and gynecology, and orthopedics resident physicians.

Background: Recent changes in anatomy curricula in undergraduate medical education (UME), including pedagogical changes and reduced time, pose challenges for foundational learning. Consequently, it is important to ask clinicians what anatomical content is important for their clinical specialty, which when taken collectively, can inform curricular development.

Methods: This study surveyed 55 non-primary care residents in anesthesiology (AN; N = 6), emergency medicine (EM; N = 15), obstetrics and gynecology (OB; N = 13), and orthopedics (OR; N = 21) to assess the importance of 907 anatomical structures across all anatomical regions.

Needs assessment of essential anatomy: The perspective of adult primary care resident physicians.

Curricular development and modification involve first identifying a problem and then performing a needs assessment, which can guide the design of curricular components. Pedagogical changes, coupled with reductions in curricular time for gross anatomy, pose challenges and impose restrictions within medical school curricula. In order to make anatomy education effective and efficient, it is important to determine the anatomy considered essential for medical education through a targeted needs assessment.

The Clinical Anatomy and Imaging Laboratory: Vertical Integration in the Preclerkship Curriculum.

Introduction: As medical schools implement integrated curricula, anatomy education especially has experienced increased pressure to make foundational content clinically relevant. We designed a novel type of integrative anatomy laboratory experience where students could use foundational anatomy concepts in concert with modern imaging/diagnostic techniques to enhance important clinical concepts.

Methods: We selected a process called Lesson Study to develop the multidisciplinary Clinical Anatomy and Imaging Laboratory (CAIL) in the cardiovascular and gastrointestinal systems.

A modified dissection method to preserve neck structures.

The neck is not only one of the more challenging anatomical regions to dissect but also has important application to clinical conditions, diseases, and procedures. In this study, we describe two simple modifications for dissection of the neck that (1) aid in the identification and preservation of the cutaneous branches of the cervical plexus and the accessory nerve, and (2) provide wide exposure of the root of the neck. The cutaneous branches of the cervical plexus can be identified with relative ease at the nerve point of the neck, where they are largest.

Chx10 is required to block photoreceptor differentiation but is dispensable for progenitor proliferation in the postnatal retina.

In the Chx10-null ocular retardation (or(J)) mouse, retinal progenitor cell (RPC) proliferation is impaired, and bipolar neurons, a late born cell type, fail to differentiate. It is unclear whether Chx10 is required to maintain proliferation throughout retinogenesis or whether the bipolar cell defect is an indirect effect of growth arrest. We show that Chx10 is dispensable for late-stage RPC proliferation but is essential to promote bipolar cell genesis in place of rods.
