The esophagus or oesophagus is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, that travels behind the trachea and heart. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The trachea is the long tube that connects your larynx to your bronchi. Bronchi send air to your lungs. Trachea is a key part of respiratory system. The trachea is made of rings of cartilage. It is lined with cells that produce mucus. Muscle contraction illustrations

It connects the scapula and the lower arm ), and consists of three sections. The upper extremity consists of a rounded head, a narrow neck, and two short processes. Its body is cylindrical in its upper portion, and more prismatic below. The lower extremity consists of 2 epicondyles, 2 processes (trochlea & capitulum), and 3 fossae (radial fossa, coronoid fossa, and olecranon fossa). As well as its true anatomical neck, the constriction below the greater and lesser tubercles of the humerus is referred to as its surgical neck due to its tendency to commonly get fractured, thus often becoming the focus of surgeons.

Motor neurons of the spinal cord are part of the central nervous system and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles, and so directly control all of our muscle movements. Muscle contraction illustrations

Interior to the muscle layer is a fluid-filled chamber called a coelom that by its pressurization provides structure to the worm`s boneless body. The segments are separated from each other by septa which are perforated transverse walls, allowing the coelomic fluid to pass between segments. Muscle contraction illustrations

Reflex is an involuntary, stereotyped response of an effector tissue that occurs when a receptor is stimulated. These reflexes are carried out by the sequential activation of a certain number of neurons that are interconnected. The last neuron usually innervates the effector tissue, which is usually a muscle.
