The correct spelling of the term "nervi subscapulares" can be a bit tricky. It refers to the subscapular nerves located under the scapula bone. In IPA phonetic transcription, it would be pronounced as /nɜrvi sʌbˈskæpjʊlərz/. The first syllable sounds like 'nerve' but with a slight emphasis on the 'n' sound. The second word, 'subscapular', starts with an 's' followed by a 'b' and a schwa sound. The final syllable, 'ares' is pronounced like 'a-res' with the emphasis on the 'a'.
Nervi subscapulares are a Latin term that refers to a specific group of nerves located underneath the scapula or shoulder blade, known as the subscapularis nerves. The subscapularis nerves are branches of the brachial plexus, a network of nerves that originate from the spinal cord in the neck and provide sensory and motor functions to the upper limb.
The nervi subscapulares are primarily responsible for innervating the subscapularis muscle, which is a large muscle situated beneath the scapula. This muscle plays a vital role in shoulder movement and stability, as it is involved in various actions such as rotating the arm inward (internal rotation) and adducting the arm toward the body. The subscapularis nerves transmit signals from the brain to the subscapularis muscle, allowing it to contract and perform these movements.
In addition to their role in motor function, the nervi subscapulares also carry sensory information from the subscapularis muscle back to the brain. This feedback helps maintain coordination and proprioception (awareness of body position) during arm movements.
Damage or dysfunction of the nervi subscapulares can result in a variety of symptoms, including weakness or paralysis of the subscapularis muscle, pain in the shoulder or upper limb, and loss of sensation. In clinical settings, injuries to the nervi subscapulares are commonly assessed, diagnosed, and treated by healthcare professionals specializing in neurology or orthopedics.

The word "nervi subscapulares" has its roots in Latin.
- "Nervi" is the plural form of the Latin word "nervus", which means "nerve".
- "Subscapulares" is derived from two Latin words: "sub" meaning "below" or "beneath", and "scapula" meaning "shoulder blade" or "shoulder bone". Therefore, "subscapulares" can be translated as "below the shoulder blade" or "underneath the scapula".
The term "nervi subscapulares" is a specific anatomical term used to describe a nerve or nerves that lie beneath or below the shoulder blade.
