ANATOMY OF EAR

HORMONE

A hormone is a chemical messenger that carries a signal from one cell to another via the blood. All multicellular organisms produce hormones.

Hormonal signalling across this hierarchy involves the following:

1.Biosynthesis of a particular hormone in a particular tissue
2.Storage and secretion of the hormone
3.Transport of the hormone to the target cell(s)
4.Recognition of the hormone by an associated cell membrane or intracellular receptor protein.
5.Relay and amplification of the received hormonal signal via a signal transduction process: This then leads to a cellular response. The reaction of the target cells may then be recognized by the original hormone-producing cells, leading to a down-regulation in hormone production. This is an example of a homeostatic negative feedback loop.
6.Degradation of the hormone.

FUNCTION OF:

The cerebral cortex is a structure within the vertebrate brain whith distinct structural and functional properties.

The hippocampus is a part of the forebrain, located in the medial temporal lobe.

The amygdalae are almond-shaped groups of neurons located deep within the medial temporal lobes of the brain in complex vertebrates, including humans.

The thalamus is a pair and symmetric part of the brain. It constitutes the main part of the diencephalon.

The ponse:
Arousal

Assists in Controlling Autonomic Functions

Relays Sensory Information Between the Cerebrum and Cerebellum

Sleep

The cerebellum:

Controls Fine Movement Coordination

Balance and Equilibrium

Muscle Tone

EXCRETORY SYSTEM

The excretion is the elimination of the toxic residues that produce the cells of our body. In this respect, also the lungs are, as both kidneys, important organs excretores, since they eliminate a toxic residue, CO2 ( Dioxide of carbon).







The blood transports other toxic different residues to CO2 Up to the kidneys and these they concentrate them up to forming a liquid which we call urine.







It is the set of organs that produce and excrete urine, the principal liquid of waste of the organism(organisation). This it happens(passes) for the uréteres up to the bladder, where it is stored up to the micturition (to (urinate).After the urine be storing in the bladder it happens(passes) for a conduit called uretra up to the exterior of the organism(organisation). The exit of the urine takes place(is produced) by the involuntary easing of a muscle: the esfínter vesical that is located between(among) the bladder and the uretra, and also for the voluntary opening of an esfínter in the uretra.





The function of the kidneys is the production of urine.


The uréter is a pipe that leads the urine towards the bladder.

CIRCULATORY SYSTEM

The Circulatory System is the main transportation and cooling system for the body.The highway system of the Circulatory System consists off a lot of one way streets. The superhighways of the circulatory system are the veins and arteries.

Veins are used to carry blood *to* the heart.

Arteries carry blood *away* from the heart.
