What are the 7 criteria used in naming muscles?
Table of Contents
Anatomists name the skeletal muscles according to a number of criteria, each of which describes the muscle in some way. These include naming the muscle after its shape, size, fiber direction, location, number of origins or its action.
What is the criteria for muscle names?
These include naming the muscle after its shape, its size compared to other muscles in the area, its location in the body or the location of its attachments to the skeleton, how many origins it has, or its action.

What are the 6 common naming categories for muscle?
Size:
- maximus – largest.
- minimis – smallest.
- vastus – huge.
- longus – longest.
- brevis – short.
- major – large.
- minor – small.
What are the 5 Golden Rules of skeletal muscle activity?
Terms in this set (5) Typically, the bulk of a skeletal muscle lies proximal to the joint crossed. All skeletal muscles have at least two attachments: the origin and the insertion. Skeletal muscles can only pull; they never push. During contraction, a skeletal muscle insertion moves toward the origin.
What criteria are used in naming muscles quizlet?
Terms in this set (8) Relative size of the muscle. Action of the muscle. Relative size of the muscle. Number of origins.
What are the 5 major properties of the muscular system?
There are 5 major properties to the muscular system.
- Excitable or Irritable.
- Contractible.
- Extensible.
- Elasticity.
- Adaptability.
What are the 5 types of muscles?
Muscle Types
- Skeletal Muscle. Skeletal muscle, attached to bones, is responsible for skeletal movements.
- Smooth Muscle. Smooth muscle, found in the walls of the hollow internal organs such as blood vessels, the gastrointestinal tract, bladder, and uterus, is under control of the autonomic nervous system.
- Cardiac Muscle.
What are the 4 types of muscles?
Different types of muscle
- Skeletal muscle – the specialised tissue that is attached to bones and allows movement.
- Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries.
- Cardiac muscle – the muscle specific to the heart.
How many attachments must a muscle have?
All muscles exert their force by pulling between at least two points of attachment. The movement that results from contraction is called the action of the muscle. Typically, one attachment remains stationary and is called the origin and the other attachment moves and is called the insertion.
What is covered by the Endomysium?
Endomysium: surrounds each single muscle fiber. A muscle fiber is known as a muscle cell. The endomysium separates the muscle fibers of a fascicle. This is a thin, delicate covering of connective tissue.
Which naming criteria were used for this muscle biceps brachii?
Answer and Explanation: The biceps brachii muscle is named using two criteria: the number of origins of the muscle, and the location of the muscle.
What features can be used to name a muscle?
The origin and/or insertion can also be features used to name a muscle; examples are the biceps brachii, triceps brachii, and the pectoralis major. 1. The location of a muscle’s insertion and origin can determine ________.
What do the names of muscle groups mean?
Some muscle names indicate the number of muscles in a group. One example of this is the quadriceps, a group of four muscles located on the anterior (front) thigh. Other muscle names can provide information as to how many origins a particular muscle has, such as the biceps brachii.
What do the prefixes in muscle names mean?
Other muscle names can provide information as to how many origins a particular muscle has, such as the biceps brachii. The prefix bi indicates that the muscle has two origins and tri indicates three origins. The location of a muscle’s attachment can also appear in its name.
What determines the name of a skeletal muscle?
The skeletal muscle’s anatomical location or its relationship to a particular bone often determines its name. For example, the frontalis muscle is located on top of the frontal bone of the skull. Other examples are muscles of the arm that include the term brachii (of the arm).
