Problem 17

Chapter 4, Problem 17

Mrs. Delancy went to the local meat market and bought a beef tenderloin (cut from the loin, the region along the steer's caudal vertebral column) and some tripe (cow's stomach). What type of muscle was she preparing to eat in each case?

Verified step by step guidance

Identify the type of muscle tissue found in the beef tenderloin. Since the tenderloin is a cut from the loin region along the steer's caudal vertebral column, it is skeletal muscle, which is attached to bones and responsible for voluntary movement.

Recognize the type of muscle tissue present in tripe, which is the lining of a cow's stomach. The stomach wall is composed primarily of smooth muscle, which is involuntary and found in the walls of hollow organs.

Understand the characteristics of skeletal muscle: it is striated, multinucleated, and under voluntary control, making it suitable for movement and posture.

Understand the characteristics of smooth muscle: it is non-striated, has a single nucleus per cell, and is controlled involuntarily to facilitate functions like digestion.

Summarize that Mrs. Delancy was preparing to eat skeletal muscle when consuming the beef tenderloin and smooth muscle when consuming the tripe.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Skeletal Muscle

Skeletal muscle is a type of striated muscle attached to bones, responsible for voluntary movements. It is characterized by long, multinucleated fibers and is the primary muscle type found in meat cuts like beef tenderloin, which comes from the loin region of the steer.

Smooth Muscle

Smooth muscle is an involuntary, non-striated muscle found in the walls of internal organs such as the stomach, intestines, and blood vessels. Tripe, which is cow's stomach lining, consists mainly of smooth muscle tissue, differing in texture and function from skeletal muscle.

Muscle Anatomy and Meat Cuts

Understanding muscle anatomy helps identify the source and type of muscle in meat products. The beef tenderloin is a skeletal muscle from the loin near the vertebral column, while tripe is derived from smooth muscle in the stomach, highlighting differences in muscle structure and culinary uses.

In adults, over 90% of all cancers arise in epithelium. Such cancers are called carcinomas, or adenomas (adenocarcinomas) if they arise in glandular epithelia. In fact, cancers of the skin, lung, colon, breast, and prostate are all in these categories. Why do you think this is so?
