Hypaxial Muscles Of A Cat

Number 2 is pointing to the external oblique muscle. The external oblique is a muscle located on the sides and front of the abdomen. It is one of the muscles responsible for the rotation and flexion of the trunk, as well as providing support to the abdominal wall.

The levator scapulae ventralis is a muscle that is located in the neck and upper back region. Its primary function is to elevate the scapula or shoulder blade. When the muscle contracts, it pulls the scapula cranially or towards the head. This movement helps in various actions such as shrugging the shoulders or tilting the head to the side.

Number 1 is pointing to the Serratus Ventralis.

The question is asking about what number 1 is pointing to. The correct answer is "Internal Oblique." This suggests that there is a diagram or image accompanying the question, and number 1 is likely a label or marker pointing to the Internal Oblique muscle.

The Transversus Abdominis is the deepest muscle sheet among the abdominal muscles. This muscle is located beneath the internal oblique muscle and runs horizontally across the abdomen. It plays a crucial role in stabilizing the spine and pelvis, as well as in supporting the internal organs. Its deep position allows it to provide a strong foundation for the abdominal wall and contribute to core strength.

The Rectus Abdominis muscle originates from the Pubis.

The scalenes are a group of muscles located in the neck, not the abdominal region. They are responsible for assisting with the movement of the neck and elevating the first two ribs during breathing. Unlike the external oblique, transversus abdominis, and internal oblique muscles, which are all located in the abdominal region and play a role in compressing and supporting the abdominal contents, the scalenes do not have any direct impact on the compression of the abdominal region.

The Transversus Abdominis muscle inserts at the linea alba, which is a fibrous structure that runs vertically down the midline of the abdomen. This muscle is located deep within the abdominal wall and is one of the core muscles responsible for stabilizing the trunk and providing support to the spine. It is unique in that it runs horizontally across the abdomen, perpendicular to the fibers of the external and internal oblique muscles. By inserting at the linea alba along with the obliques, the Transversus Abdominis helps to reinforce the midline and provide additional strength and stability to the abdominal region.

The serratus dorsalis muscle originates from the middorsal fascia. The middorsal fascia is a connective tissue located in the midline of the back. It serves as an attachment point for various muscles, including the serratus dorsalis. This muscle is responsible for the movement and stabilization of the ribs and spine. By originating from the middorsal fascia, the serratus dorsalis can effectively perform its functions and contribute to the overall movement and support of the back.

The rhomboideus complex is a group of muscles located in the upper back. These muscles are responsible for retracting and elevating the scapula, which is commonly known as the shoulder blade. Therefore, the correct answer is Scapula.

The insertion of serratus ventralis is the vertebral border of the scapula. This means that the muscle attaches to the inner edge of the scapula bone.

The Serratus Dorsalis originates from the middorsal fascia. This muscle is located on the lateral side of the thoracic vertebrae and is responsible for assisting in the movement of the ribs during breathing. It helps to expand the rib cage and aids in stabilizing the thoracic spine. The origin of the Serratus Dorsalis from the middorsal fascia allows it to have a strong attachment to the spine, providing stability and support for the surrounding structures.

The serratus dorsalis is a muscle that is located on the side of the thorax. It originates from the spinous processes of the upper thoracic vertebrae and inserts on the outer surface of the ribs. This muscle helps in the movement and stabilization of the ribcage during breathing. Therefore, the correct answer is "Ribs".

The muscle that retracts the ribs is the Intercostalis Internus. This muscle is located between the ribs and is responsible for pulling the ribs downward during exhalation, helping to decrease the volume of the thoracic cavity. This action assists in the process of breathing by aiding in the expulsion of air from the lungs.

The external oblique muscle in Necturus is homologous to the Serratus Dorsalis, Serratus Ventralis, and Scalenes muscles. However, the Levator Scapulae Ventralis muscle is not homologous to the external oblique in Necturus.

The external oblique muscles run craniodorsally.

The rhomboideus complex is a group of muscles located in the upper back that help stabilize and retract the scapula. It is not homologous with any portion of Necturus. The external oblique is a muscle located on the lateral sides of the abdomen that helps with rotation and lateral flexion of the trunk.

The action of the scalenes is to bend the neck and pull the ribs cranially. The scalenes are a group of three muscles located in the neck, and they play a role in various movements and stabilization of the neck and ribcage. When the scalenes contract, they help in flexing and rotating the neck, as well as elevating the first and second ribs. This action is important for various activities such as breathing, turning the head, and maintaining proper posture.
