Examples of this type of tissue in the body include the heart, stomach, and blood vessels. Smooth muscles consist of those tissue types which are found within the walls of hollow internal organs. Each of these types of tissue serves a different purpose in the body of a dog and is under the control of either the voluntary or involuntary system. The muscle anatomy of a dog consists of three main types of muscle tissue: smooth muscle, skeletal muscle, and cardiac muscle. Involuntary muscles include the heart, diaphragm, and intestines. The brain automatically regulates the functions of these muscles to keep a dog alive. Involuntary muscles are not controlled by conscious thought, but rather are controlled and managed by the brain using the autonomic nervous system. The other half of the puzzle consists of involuntary muscles in the body. These impulses force the contraction of those muscles groups and engage the shoulders, adduct and abduct of the legs, and control the hip as a dog runs. In deciding to run after a ball, the dog’s brain sends electrical impulses through the nervous system to muscles such as the infraspinatus, pectoral, trapezius, biceps brachii, and gluteal muscle to facilitate movement. The decision to chase a ball across the yard involves a conscious choice by a dog. Voluntary muscles are those within the body of dog which can be directly controlled by conscious thought. Just as in the human body, the muscle anatomy of a dog consists of both voluntary and involuntary control. These muscles flex as part of the operation of these various organs and are under the involuntary control in the brain. The other muscle groups of the body are built-in, for a lack of better terminology, to the internal organs of the body such as the heart, diaphragm, and intestines. As these muscles contract, the tendons are pulled on, and in turn pull on the bones to create movement in the limbs. Tendons, which are elastic and strong tissue fibers, form the connection between skeletal muscles and bones. Skeletal muscles, also known as striated muscles, are those which connect directly to bones in the skeletal system. These impulses are converted into a form of mechanical energy in muscles that forces it to contract, thereby producing movement.Ĭonnective tissue that hold muscles together in a dog’s body can differ based upon the type of tissue they form a connection with. Muscle fibers in a dog’s body receive electrical impulses from the brain via the central nervous system. Connected to the skeletal system, skin, and other muscles, each muscle in the body helps to create movement. The muscles found in the body of every dog are composed of a mass of cells held together by connective tissues. This particular dog uses Bully Max™ supplements along with moderate exercise to achieve this amazing physique. Structure of Muscle Systems Pictured above shows the dog muscle anatomy of the canine. An equally important function for muscles is to provide stability to the joints of the body, making it easier for them to function under pressure. The first, and most obvious, is to facilitate movement of the limbs, head, neck, and joints. The muscle anatomy of a dog serves two important purposes. From here, it becomes too difficult to compare the muscle anatomy of dogs and humans. Additionally, both muscular systems use the power of contraction to produce movement. Just as the human muscular system is composed of units of tissue connected to the skeletal system, skin, and other muscles, a dog’s muscle anatomy is arranged in a similar fashion. The muscular anatomy of a dog, while serving the same purpose in a dog, differs in structure and function from the muscular system in a human body. However, since dogs do not share the same body type as a human, that means it has a different musculoskeletal system than humans. Like other mammals on planet Earth, dogs have a complex skeletal and muscular system designed to support both voluntary and involuntary movements. An Introduction to the Muscle Anatomy of DogsĪny dog owner that has run playfully through the backyard or a local park with their beloved pet has no doubt marveled at the speed and graceful maneuverability a dog possesses. It’s the ideal diet to excel dog muscle growth. Ace uses Bully Max™ along with a 30/20 (30% Protein, 20% Fat) kibble. Ace’s most predominant muscles are his triceps, Bicep Femoris, Scapular Deltoid, Acromion Deltoid, and his lower Trapezius. Pictured above is Ace from DarkDynastyK9s, arguably one of the most muscular dogs in the world.
