Origin of latissimus dorsi

Origin of Latissimus Dorsi Muscle Depending on the origin one can distinguish four parts Vertebral part originating from the spinous processes of the 7th to 12th thoracic vertebrae and the thoracolumbar fascia. This muscle does not work alone.

The latissimus dorsi is considered an extrinsic muscle of the back meaning a muscle that originates from the myogenic cells in the developing upper limb buds rather than from the myotomal dorsal epaxial division of the somite where the intrinsic deep back muscles will take origin.

Origin of latissimus dorsi. Spinous processes of vertebrae T7-L5 thoracolumbar fascia iliac crest inferior 3 or 4 ribs and inferior angle of scapula. The latissimus dorsi is a large flat muscle covering the width of the middle and lower back. It connects the bone of the upper arm to the spine and the hip.

This muscle is often referred to as the lats. The latissimus dorsi muscle is one of the largest muscles in the back. There muscle is divided into two segments which are configured symmetrically along.

Latissimus Dorsi is a large flat triangular muscle that covers a large area of the lower back and is overlapped by the trapezius.

It is also known as Broadest muscle of the back. The muscle runs between the trunk via an extensive attachment and the humerus by a narrow tendon. It therefore acts on the shoulder joint.

Origin -It originates from. Latissimus Dorsi Muscle. Latissimus Dorsi is one of four muscles responsible for the thoracobrachial motion.

It is large flat and triangular in shape originating from large parts of the lumbar region and lower thorax to insert on the humerus through a narrow tendon. Origin of the latissimus dorsi is from spinous processes of thoracic T7T12 thoracolumbar fascia iliac crest and inferior 3 or 4 ribs inferior angle of scapula and insertion on floor of intertubercular groove of the humerus. The latissimus dorsi may be used for the tendon graft surgeries.

The latissimus dorsi is considered an extrinsic muscle of the back meaning a muscle that originates from the myogenic cells in the developing upper limb buds rather than from the myotomal dorsal epaxial division of the somite where the intrinsic deep back muscles will take origin. Origin of the latissimus dorsi is from spinous processes of thoracic T7T12 thoracolumbar fascia iliac crest and inferior 3 or 4 ribs inferior angle of scapula and insertion on floor of intertubercular groove of the humerus. The latissimus dorsi may be used for the tendon graft surgeries.

The latissimus dorsi is one of the largest and strongest muscles in the back. Be sure to check out this lesson for more interesting facts about this muscle including its origin innervation and. Origin of the latissimus dorsi is from spinous processes of thoracic T7T12 thoracolumbar fascia iliac crest and inferior 3 or 4 ribs inferior angle of scapula and insertion on floor of intertubercular groove of the humerus.

The latissimus dorsi is the broadest largest muscle of the back. Latissimus Dorsi actions mainly are Extension Adduction and Internal Rotation of the upper limb. Attachment of the Latissimus Dorsi Origin.

Ilium-Posterior iliac Crest Sacrum -Posterior Vertebral Column -Laterally Thoracic Vertebrae T7-12 Lumbar Vertebrae L1-5 thoracolumbar fascia Ribs Posterior. The latissimus dorsi muscle whose name means broadest muscle of the back is one of the widest muscles in the human body. Also known as the lat it is a large flat triangular muscle that is not used strenuously in common daily activities but is an important muscle in many exercises such as pull-ups chin-ups lat pulldowns and swimming.

Origin of Latissimus Dorsi Muscle. Depending on the origin one can distinguish four parts. Vertebral part originating from the spinous processes of the 7th to 12th thoracic vertebrae and the thoracolumbar fascia Iliacal part starting from the iliac crest Costal part having origins from the 9th to 12th ribs.

Scapular part starting from the inferior angle of the scapula inconstant. The muscle may arise only from the ribs rather from the vertebral column ribs scapula and the crest of the ilium as is most common. The costal origin may be reduced to rib 12.

Mori has reported the vertebral costal and scapular origins for latissimus dorsi from 50 Japanese cadavers 100 halves as follows. Origin of the latissimus dorsi is from spinous processes of thoracic T7T12 thoracolumbar fascia iliac crest and inferior 3 or 4 ribs inferior angle of scapula and insertion on the floor of intertubercular groove of the humerus. The latissimus dorsi may.

Latissimus dorsi origin and insertion is described in more detail below. This muscle does not work alone. An entire group of different muscles move the shoulders and arms.

These include the pectoralis major latissimus dorsi trapezius serratus anterior and deltoid muscles. Another important muscle group is the rotator cuff. Hey guysThis series of videos relates to the muscles that attached to the humerus and move the shoulder joint.

Today we look at the Latissimus dorsiI use t. Spinous processes of T7 to T12 iliac crest thoracolumbar fascia 3rd 4th most inferior ribs and inferior angle of the scapulaIn.
