The acromiotrapezius, spinotrapezius, and latissimus dorsi all attach along the dorsal midline to several key bones. The acromiotrapezius attaches to the spine of the scapula and the cervical and thoracic vertebrae. The spinotrapezius primarily connects to the spinous processes of the thoracic vertebrae. The latissimus dorsi attaches to the spinous processes of the lower thoracic, lumbar vertebrae, and the iliac crest.
Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.
"Infundibulum is midline" refers to a structure called the infundibulum which lies in the midline of the body. The term highlights the specific location of the infundibulum along the midline of the body.
Toward the midline means in the direction of the middle of the body. "Medial" means located closer to the midline, and adduction is movement of the limbs towards the midline.
Yes, abduction is movement away from the midline of the body. It occurs in the frontal plane and is the opposite of adduction, which is movement towards the midline.
The relatively fixed point of a muscle's attachment to a bone is called the origin. It is typically located closer to the body's midline and usually remains stationary during muscle contraction.
. The insertion is considered the moveable part, or the part that attaches farthest from the midline or center of the body. The insertion in known as the distal attachment.
No, the upper arm is proximal to the forearm. The term "distal" is used to describe structures that are further away from the body's midline or point of attachment, while "proximal" refers to structures that are closer to the body's midline or point of attachment.
Linea Alba
The band of tough connective tissue in the midline of the anterior wall is called the linea alba. It serves as an attachment site for abdominal muscles, providing support and stability to the abdominal wall.
Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.
An example of an aponeurosis is the linea alba, which is the white fibrous band that runs down the midline of the abdomen and serves as an attachment site for abdominal muscles.
The bony projection that arises at right angles to the midline on your back is called a "transverse process." These projections are found on the vertebrae and serve as attachment points for muscles and ligaments, contributing to the stability and movement of the spine.
"Infundibulum is midline" refers to a structure called the infundibulum which lies in the midline of the body. The term highlights the specific location of the infundibulum along the midline of the body.
Toward the midline means in the direction of the middle of the body. "Medial" means located closer to the midline, and adduction is movement of the limbs towards the midline.
Fingers and toes are lateral to each other. "Lateral" means toward the side of the body or away from the midline, while "proximal" means closer to the center of the body or closer to the attachment point.
Para-midline is used to describe a place on an animal, the para-midline is a line that runs on the side of the midline, but not above it. This is a term generally used by veterinarians.
Yes, abduction is movement away from the midline of the body. It occurs in the frontal plane and is the opposite of adduction, which is movement towards the midline.
