Many functions of the spinal cord are also executed independently from the brain, such as a spinal reflex. The definition of a spinal reflex as well as their components, functions, pathways, and physiology will be described in this article and is a must-know for every student that is passionate about neurosciences. Biceps brachii, triceps
Triceps brachii. This muscle , usually referred to as your triceps, runs along your humerus and allows for the flexion and extension of your forearm. It also helps to stabilize your shoulder joint.
The forearm is the section of the upper limb from the elbow to the wrist, whose bony structure is formed by the radius (laterally) and ulna (medially). Two muscular compartments - an anterior (flexor) and posterior (extensor) compartment - contain together twenty muscles that act on the elbow and wrist joints, as well as carpometacarpal, metacarpophalangeal, and interphalangeal joints of the hand.
Structure and Function. Anatomy. The teres major originates on the posterior surface of the inferior angle of the scapula and inserts on the medial lip of the intertubercular groove of the humerus. It is located inferior to the teres minor and travels anterior to the triceps long head before inserting on the humerus.
Primary functions of the triceps are elbow extension (straightening of the arm), arm adduction (bringing your arms closer to your body), and shoulder stability. 4. Size. The triceps is a larger muscle, accounting for about two-thirds of the volume of the upper arm, whereas the biceps accounts for roughly one-third of the total volume.
Studies of actions performed by standing persons revealed two stable muscle modes with opposing action: One of the modes united muscles on the dorsal side of the body (such as triceps surae, hamstrings, and erector spinae) while the other mode united muscles on the ventral side of the body (such as tibialis anterior, quadriceps, and rectus
