Microscopic Views of Skin, Bone, and Muscle
Learning Objective
I can describe and distinguish skin, bone, and muscle tissues under a microscope.
Key Concepts
Striations, or light and dark stripes, are clearly visible in skeletal muscle.
Intercalated discs are only found in cardiac muscle, which also has a branched appearance.
Smooth muscle has neither striations nor intercalated discs.
Practice Questions
This lesson includes 8 practice questions to reinforce learning.
