What is the name of the large thick muscle located on either side of the lumbar vertebrae?
The large thick muscle located on either side of the lumbar vertebrae is called the erector spinae. Its main function is to extend and laterally flex the spine.
What structure connecting the pectoral muscle to the humerus?
The structure connecting the pectoral muscle to the humerus is the tendon of the pectoralis major muscle. This tendon attaches the muscle to the upper arm bone (humerus), allowing for movements like shoulder flexion, adduction, and medial rotation.
What is a vertebra with block like body and short stout spinous process?
That is likely a lumbar vertebra, which has a block-like body to support weight bearing and a short, stout spinous process for muscle attachment and stability. The lumbar vertebrae are larger and sturdier compared to other vertebrae in the spine to help support the lower back and trunk.
When the muscle contracts what happens to the tendon and bone?
When the muscle contracts, the tendon pulls on the bone to create movement. The tendon is the connective tissue that attaches the muscle to the bone, so when the muscle contracts, it exerts force on the tendon, which in turn moves the bone.
What is the name for a muscle attached at only one end?
A muscle attached at only one end is called unipennate muscle. It has a single tendon and its muscle fibers run diagonally to the tendon.

What muscles attaches to the lumbar vertebrae and femur?
The primary muscles that attach to the lumbar vertebrae and the femur include the psoas major and the iliacus, which together form the iliopsoas muscle. The psoas major originates from the lumbar vertebrae and inserts onto the lesser trochanter of the femur, playing a crucial role in hip flexion. Additionally, the quadratus lumborum muscle, which stabilizes the lumbar spine, indirectly influences the femur's position through its connection to the pelvis.
Is the strip of tissue connecting the kneecap to the thigh muscle an example of a tendon?
Yes, the strip of tissue connecting the kneecap to the thigh muscle is known as the patellar tendon, which is indeed an example of a tendon. Tendons are tough bands of connective tissue that connect muscles to bones, allowing for movement and stability in the body.
Describe the attachments of the diaphragm?
The diaphragm has peripheral attachments to structures making up the abdominal and chest walls. These attachments have muscle fibers that converge in the central tendon, forming the crest of the dome.
Is a quadricep tendon a flexor or extensor tendon?
Dorsi flexion and eversion are its main actions. I just can't justify this your question.
How many cervical thoracic and lumbar vertebrae are there?
Absolutely! They have features unique to the region they are found in, relating to structure and therefore function. Typical cervical vertebrae (C3-C6) usually have bifid spinous processes which point slightly inferiorly. The spinous processes on lumbar vertebrae are oblong in shape and point directly posteriorly. The articular facets of cervical vertebrae face superior-inferiorly, whereas lumbar articular facets face medial-laterally. Cervical vertebrae have transverse foramen on right and left(containing the vertebral arteries), lumbar have none. They have mamillary processes on their superior articular processes. The bodies of lumbar vertebra are larger and thicker than cervical vertebrae, though they are oval/kidney shaped shaped in both regions. The transverse processes of lumbar vertebrae are much longer, for muscle attachment. Cervical vertebrae have anterior and posterior tubercles extending from their transverse processes. The pedicles of lumbar vertebrae are slightly longer and more defined than those of cervical vertebrae. I think that covers everything, let me know if you think of anything else!
What is a sentence using the word sinew?
(sinew is another word for ligament, connecting bone to muscle, or tendon, connecting muscles)The damaged sinew in its leg meant that the racehorse had to miss the race.
Cord of connective tissue that joins a muscle to a bone?
The part of anatomy that fits this description is the tendon, which attaches the muscle to bone.
Does connective tissue connect tissue?
Connective tissue connects tissues to tissue. A good example is muscle (a tissue) connecting to bone (a tissue). The tissue that does THIS is called a tendon. A tendon connects muscles to bones.
What is a common name for the latissimus dorsi?
The origins of the latissimus dorsi are: - spinous processes of the lower six thoracic vertebrae - lumbar vertebrae - sacral vertebrae - lower three or four ribs
What is an antonym for the word tendon?
Muscle or Bone. A tendon connects a muscle and bone together but is not a muscle or bone.
