Integration Week 10

You press one of Snoopy's skin lesions against a glass slide and stain it with Wright-Giemsa. What cells are predominantly shown in the image?

When you performed a physical exam on Snoopy, you lightly touched his lateral thorax and noticed that his skin twitched. What is the name of the muscle causing the skin twitching?

What is the name of the fatty substance coating axons?
(Hints: It helps to accelerate the speed of information transfer along the axon length.)

What protein is skin primarily composed of?

What is the layer of the epidermis that consists of several layers of flattened cells that contain keratohyalin granules?

What is the main activated (cleaved) complement component, which has a potent chemotactic effect on neutrophils?

What is this structure indicated by #2 in the diagram?

What is the structure highlighted by the black arrow in this histology image of the skin?

The axillary lesions on Snoopy extend along the proximal forelimb to the biceps brachii muscle. What is the name of the nerve that innervates this muscle?

What are the structures indicated by #1 in the diagram?

(Hints: their function is to transmit electrical impulses to the neuronal cell body)
