Recent studies have identified genetic factors that confer an increased risk of SZ and participate in the disease etiopathogenesis. In parallel to such bottom-up approaches, other studies have extensively reported biological changes in patients by brain imaging, neurochemical and pharmacological approaches. This review highlights the molecular substrates identified through studies with SZ patients, namely those using top-down approaches, while also referring to the fruitful outcomes of recent genetic studies. is the brain part of the endocrine system

GCSE Biology - Endocrine System \u0026 Hormones #40Insect physiology includes the physiology and biochemistry of insect organ systems. Although diverse, insects are quite similar in overall design, internally and externally.
The insect is made up of three main body regions tagmatathe head, thorax and abdomen. The head comprises six fused segments with compound eyesocelliantennae and mouthparts, which differ according to the insect's particular diet, e. The thorax is made up of three segments: the pro, meso and meta thorax, each supporting a pair of legs which may also differ, depending on function, e.
Usually the middle and the last segment of the thorax have paired wings. The abdomen generally comprises eleven segments and contains the digestive and reproductive organs. An insect uses its digestive system to extract nutrients and other substances from the food it consumes. This break-down process is known as digestion. The insect's digestive system is a closed system, with one long enclosed coiled tube called the alimentary canal which runs lengthwise through the body. The alimentary canal only allows food to enter the mouth, here then gets processed as it travels toward the anus. The alimentary canal has specific sections for grinding and food storage, enzyme production, and nutrient absorption.
The three regions include the foregut stomatodeum 27, the midgut mesenteron 13 bran, and the hindgut proctodeum In addition to the alimentary canal, insects also have paired salivary glands and salivary reservoirs. These structures usually reside in the thorax adjacent to the fore-gut. The salivary glands 30 produce is the brain part of the endocrine system the salivary ducts lead from the glands to the reservoirs and then forward through the head to an opening called the eystem behind the hypopharynx ; which movements of the mouthparts help mix saliva with food in the buccal cavity. Saliva mixes with food, which travels through salivary tubes into the mouth, beginning the process of breaking it down. The stomatedeum and proctodeum are invaginations of the thd and are lined with cuticle intima. The mesenteron is not lined with cuticle but with rapidly dividing and therefore constantly replaced, epithelial cells.
The main function of insect blood, hemolymph, is that of transport and it is the brain part of the endocrine system the insect's body organs.

It also plays an essential part in the moulting process. It can contain unpalatable and malodourous chemicals that will act as a deterrent to predators.
Hemolymph contains molecules, ions and cells. Body fluids enter through one way valved ostia which are openings situated along the length of the combined aorta and heart organ. Pumping of the hemolymph occurs by waves of peristaltic contraction, originating at the body's posterior end, pumping forwards into zystem dorsal vessel, out via the aorta and then into the head where it flows out into the haemocoel. Insect respiration is accomplished without lungs using a system of internal tubes and sacs through which gases either diffuse or are actively pumped, delivering oxygen directly to tissues that need oxygen and eliminate carbon dioxide via is the brain part of the endocrine system pf.
Air is taken in through spiraclesopenings which are positioned laterally in the pleural wall, usually a pair on the anterior margin of the meso and meta thoraxand pairs on each of the eight or less abdominal segments, Numbers of spiracles vary from 1 to 10 pairs. Carbon dioxide leaves the body by the same process.
Introduction
The major tracheae are thickened spirally like a flexible vacuum hose to prevent them from collapsing and often swell into air sacs. Larger insects can augment the flow of air through their tracheal system, with body movement and rhythmic flattening of the tracheal air sacs. There are many different patterns of gas exchange demonstrated by different groups of insects.]
I understand this question. Is ready to help.
It seems magnificent idea to me is
It is scandal!
You are mistaken. Write to me in PM, we will communicate.
