Introduction The facial nerve is also called the seventh cranial nerve (CN7). This nerve has two main functions. It transmits sensory information from the tongue and the inside of the mouth. CN7 specifically serves the tip of the tongue, accounting for roughly two-thirds. The nerve extends from the brain stem to the pons and medulla….
The teres minor muscle is a small yet vital muscle located in the posterior shoulder region. Together with the infraspinatus muscle, it forms part of the rotator cuff, a group of muscles and tendons crucial for stabilizing and providing mobility to the shoulder joint. The rotator cuff’s teres minor is an elongated, thin muscle. The…
The teres major muscle, despite its relatively small size, plays a significant role in the movement and stability of the shoulder joint. Situated in the upper back region, it forms part of the rotator cuff group, which comprises muscles crucial for shoulder function. What Is The Teres Major Muscle? Stretching from the inferior posterior scapula…
The trapezius muscle is one of the major muscles of the upper back and neck region in humans. It is a large, triangular muscle that extends from the base of the skull, down the spine, and out to the shoulder blades. Its distinctive shape resembles a trapezoid, hence its name. What Are The Trapezius Muscles?…
Introduction The hamstring vs quadriceps are two of the most significant muscle groups in the human body, which are essential for both movement and sports performance. The hamstrings are three muscles on the back of the thigh, and the quadriceps are four muscles on the front of the thigh. Both are found in the upper…
The sartorius muscle, often referred to as the “tailor’s muscle,” is the longest muscle in the human body, running from the anterior superior iliac spine (ASIS) of the pelvis to the medial side of the tibia. This long, ribbon-like muscle plays a significant role in hip and knee flexion, as well as aiding in the…
What Is The Infraspinatus Muscle? The infraspinatus muscle is a key anatomical structure located in the shoulder region of the human body. It is one of the four muscles that make up the rotator cuff, a group of muscles and their tendons that provide stability and facilitate various movements of the shoulder joint. Thick, trapezoidal…
What Is The Supraspinatus Muscle? The supraspinatus muscle is one of the four muscles that make up the rotator cuff, a group of muscles and tendons that stabilize the shoulder joint and facilitate its movement. It is located on the superior aspect of the scapula (shoulder blade) and plays a crucial role in initiating the…
The triceps brachii muscle, commonly called the triceps, is a big muscle located on the back of the upper arm. It is responsible for the extension of the elbow joint, straightening the arm, and aiding in movements such as pushing and lifting. What is the Triceps Muscle? The triceps brachii is the only muscle that…
What is a V M O Muscle (Vastus Medialis Oblique)? The V M O Muscle (Vastus Medialis Oblique) is a quadriceps muscle in the thigh. The quadriceps femoris is a group consisting of four muscles on the front of the thigh, including the VMO. The quadriceps have the responsibility of extending the knee and play an…
