Key Terms Chapter 10 Flashcards
The scientific study of muscles is ______
Myology
Three types of muscular tissue include:
Skeletal muscle tissue, cardiac muscle tissue, and smooth muscle tissue
Built-in rhythm that initiates contractions involuntarily
Autorhythmicity
AS muscular tissue contracts, it produces heat, a process known as ________.
Thermogenesis
Four key functions of muscular tissue:
Producing body movements, stabilizing body positions, storing and moving substances within the body, and generating heat.
Four special properties of muscular tissue:
Electrical excitability, contractility, extensibility, and elasticity.
Another name of a muscle cell is _____
Muscle fiber due to their elongated shape
The _______ separates muscle from skin and is composed of areolar connective tissue and adipose tissue.
Subcutaneous layer or hypodermic
A dense sheet or broad band of irregular connective tissue that lines the body wall and limbs and supports and surrounds muscles and other organs of the body
Fascia
The outer layer of dense irregular connective tissue that encircles the entire muscle
Epimysium
A layer of dense irregular connective tissue that surrounds a group of 10 or more muscle fibers separating them into fascicles.
Perimysium
Made up of mostly reticular fibers, this penetrates the interior of each fascicle and separates individual muscle fibers from one another.
Endomysium
The plasma membrane of a muscle cell
Sarcolemma
The cytoplasm of a muscle fiber
sarcoplasm
This protein, found only in muscle, binds oxygen molecules that diffuse into muscle fibers from interstitial fluid and releases it when needed by the mitochondria for ATP production.
Myoglobin
