What is the action of Xiphihumeralis?
action: assists pectoralis minor - adducts arm.
Do humans have Xiphihumeralis?
The two muscles that cats have that humans do not are the xiphihumeralis and the pectoantebrachialis muscles.
What is the function of the Pectoantebrachialis?
The major action of these muscles is adduction of the forelimb (i.e. the front leg is drawn toward the midline). There are four subdivisions of the pectoral group in the cat. The pectoantebrachialis is the most superficial muscle of the pectoral group.
Do cats have pec muscles?
This cat illustrates the three pectoralis muscles: the pectoantebrachialis, the pectoralis major, and the pectoralis minor. One way to find the pectoantebrachialis is to stretch the forelimbs of the cat which will reveal the bordering fascia. This muscles goes straight across the chest and to the forelimbs.
Do humans have a Clavotrapezius?
5. clavotrapezius, acromiotrapezius, spinotrapezius – three muscles in cat, one muscle in human (trapezius).
What is the Spinotrapezius?
Spinotrapezius, also called thoracic trapezius, is the most posterior of the three trapezius muscles. It is triangular shaped. Posterior to the acromiotrapezius and overlaps latissimus dorsi on the front. Its origin is the neural spines of the thoracic vertebrae and its insertion is the scapular fascia.
Where is the Clavobrachialis located?
Clavobrachialis (Clavodeltoid) - This is the most anterior muscle in the shoulder and arm region. It originates at the clavicle, crosses the shoulder and upper arm, and inserts upon the ulna near the elbow.
Why does my rectus abdominis hurt?

Why are humans so special?
Humans are unusual animals by any stretch of the imagination. Our special anatomy and abilities, such as big brains and opposable thumbs, have enabled us to change our world dramatically and even launch off the planet.
Are all humans the same species?
The billions of human beings living today all belong to one species: Homo sapiens. As in all species, there is variation among individual human beings, from size and shape to skin tone and eye color.
How long have humans been around?
around 300,000 years agoFossils and DNA suggest people looking like us, anatomically modern Homo sapiens, evolved around 300,000 years ago. Surprisingly, archaeology – tools, artefacts, cave art – suggest that complex technology and cultures, “behavioural modernity”, evolved more recently: 50,000-65,000 years ago.
