Chapter 9, Problem 4SQ

a.

Summary Introduction

To describe: The sources of energy for skeletal muscle contraction.

Concept introduction: In the human body, the musculoskeletal system includes the muscles, bones, and joints. Muscle tissues are long and fibrous excitable cells that help in the muscle contraction of the body. They can be classified into three types – skeletal, cardiac, and smooth muscle tissues. The skeletal muscles are the voluntary muscles which help in the movement of bones and other structures.

b.

Summary Introduction

To explain: The effect of a cholinergic blocking agent on skeletal muscle contraction.

Concept introduction: In the human body, the musculoskeletal system includes the muscles, bones, and joints. Muscle tissues are long and fibrous excitable cells which help in the muscle contraction of the body. They can be classified into three types – skeletal, cardiac, and smooth muscle tissues. The skeletal muscles are the voluntary muscles which help in the movement of bones and other structures.

c.

Summary Introduction

To explain: The way in which anabolic steroid drugs affects skeletal muscle.

Concept introduction: In the human body, the musculoskeletal system includes the muscles, bones, and joints. Muscle tissues are long and fibrous excitable cells which help in the muscle contraction of the body. They can be classified into three types – skeletal, cardiac, and smooth muscle tissues. The skeletal muscles are the voluntary muscles which help in the movement of bones and other structures.

d.

Summary Introduction

To describe: The purpose and structure of a tendon.

Concept introduction: In the human body, the musculoskeletal system includes the muscles, bones, and joints. Muscle tissues are long and fibrous excitable cells which help in the muscle contraction of the body. They can be classified into three types– skeletal, cardiac, and smooth muscle tissues. The skeletal muscles are the voluntary muscles which help in the movement of bones and other structures.

e.

Summary Introduction

To describe: The outcome after part of a muscle has died.

Concept introduction: In the human body, the musculoskeletal system includes the muscles, bones, and joints. Muscle tissues are long and fibrous excitable cells which help in the muscle contraction of the body. They can be classified into three types – skeletal, cardiac, and smooth muscle tissues. The skeletal muscles are the voluntary muscles which help in the movement of bones and other structures.
