Editing Head

'''Head'''

The '''head''' is the part of an organism which usually includes the [[brain]], eyes, ears, nose and mouth, each of which aid in various sensory functions such as sight, hearing, smell, and taste, respectively.<ref>https://www.wikimd.com/wiki/Head</ref> Some very simple animals may not have a head, but many bilaterally symmetric forms do, regardless of actual complexity.

== Anatomy ==

The human head consists of a [[brain]], usually three [[sense organ]]s, one [[bilateral]], two [[eye]]s, and two [[ear]]s, plus three [[collective sense organ]]s, one [[mouth]], one [[nose]], and one [[tongue]].

=== Brain ===

The [[brain]] is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision.

=== Eyes ===

The [[eye]] is a sensory organ that allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth.

=== Ears ===

The [[ear]] is the organ that detects sound. It not only receives sound, but also aids in balance and body position.

=== Nose ===

The [[nose]] is the organ that allows for the sense of smell. The cavity of the nose is lined with mucous membranes that have smell receptors connected to the olfactory nerve.

=== Mouth ===

The [[mouth]] is the first part of the alimentary canal that receives food and produces saliva. The mouth also contains the [[tongue]] and the [[teeth]].

== Function ==

The head houses the brain which controls the body. The head is also the sensory interface with the environment, collecting information from the senses of sight, smell, taste, touch, and hearing.
