Skeletal Muscle Contraction

*Neuromuscular junction -Plays an essential role in the function of skeletal muscle. It helps to transfer the electrical impulses from the central nervous system to the muscle fibers. -In the anterior gray horn, there are cell bodies of the somatic nervous system (system that controls the skeletal muscle and it is under voluntary control). -From

Lymphatic System

*Overall information: -Blood is carried from the heart to every part of your body to provide nutrients. There are nearly 20 liters of blood plasma being filtered through capillaries. Then, the remaining fluid (lymph) moves directly to the veins and back to the heart, but there are some escaping from capillaries and cells. Thus, the

Muscular System

-It is responsible for the movement of our body. -There are about 700 muscles with specific names, making up approximately half of the body’s weight.  -Muscle system includes three types of muscle tissue: smooth, cardiac, and skeletal.  *Smooth Muscles (visceral muscle) -Found in the stomach, small and large intestines, arteries, veins,… -Very essential for respiratory,

Spinocerebellar tract

*Overall information: -Spinocerebellar tract is an ascending pathway that responds to proprioception (unconscious awareness of the positions of our limbs in space), touch, pressure and goes from the spinal cord to the cerebellum (posture, balance, muscle tones, coordination of muscle movement controller) -It is divided into 4 specific sub-tracts: dorsal spinocerebellar tract (DST), ventral spinocerebellar

Spinothalamic tract

* Music boosts your IQ and EQ. Try my favorite music before reading this article *Overall information: -The spinothalamic tract is an ascending pathway of the spinal cord. It is responsible for carrying pain, temperature, pressure and crude touch from our skin surface to the thalamus in the brain before reaching the primary sensory cortex.
