There are several muscles involved in breathing:
Scalenes (Elevate rib cage, assist in inhalation)
Sternocleidomastoid (Elevate Rib Cage, assist in inhalation)
Pectoralis minor (Elevate Rib Cage, assist in inhalation)
External Intercostals (Elevate rib cage, assist in inhalation)
Internal Intercostals (Depress, assist in exhalation)
Diaphragm (Prime mover of inhalation)
When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity.
The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
What else can I help you with?
Is a pectoralis major muscle a heart muscle?
No, it is not. It is the large chest muscle.
What is the large flat muscle at the bottom of the chest activity called?
The large flat muscle at the bottom of the chest is called the diaphragm. It plays a crucial role in respiration by contracting and expanding to facilitate breathing. When the diaphragm contracts, it creates a vacuum that allows air to flow into the lungs. It separates the thoracic cavity from the abdominal cavity.
What is the large muscle on the front of the chest?
Pectorals
What is the large muscle on the floor of a chest cavity that helps you breathe?
diaphragm
What is the large band of muscle that controls the size of the chest cavity?
The heart you idiot!
Is the diaphragm the large band of muscle that controls the size of the chest activity?
Yes it is.
The large round muscle at the base of the chest is the?
m. teres minor and major
The large muscle of the upper chest that flexes the arm across the body is the?
Pectoralis major
What is the large flat muscle that moves up and down to alter the volume of the chest?
diaphragm
What is the large medial area of the chest is called?
The large medial area of the chest is called the sternum. It is a flat bone located in the center of the chest, and serves as an attachment point for ribs and some chest muscles.
What is the anatomy of the breast muscle?
The breast muscle, also known as the pectoralis major, is a large, fan-shaped muscle located in the chest area. It is composed of two main parts: the clavicular head and the sternal head. The clavicular head originates from the collarbone (clavicle) and the sternal head originates from the sternum (breastbone). These two parts come together to form the bulk of the chest muscle, which is responsible for movements like pushing and hugging.
What is the large medial area of the chest?
The large medial area of the chest is called the sternum. It is a flat bone located in the center of the chest and connects to the ribs. The sternum plays a crucial role in protecting the heart and lungs.
