Question

Chapter 7, Problem 3IP

Summary Introduction

To construct: Chart listing all muscles crossing the wrist joint according to whether they are medial, lateral, anterior, or posterior to the joint center and identify the actions performed by the muscles listed in the four categories.

Concept introduction: Muscles are soft tissues. Muscles are classified as skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscles contract and relax with the bones and they help in locomotion, gait and respiration. The articulating connection also known as the joint is the connection between two bones that help both the bones to perform the same function in synchronized fashion.
