1.A small glandular organ that is situated behind the top of the breastbone, consisting mainly of lymphatic tissue and serving as the site of T cell differentiation. The thymus increases gradually in size and activity until puberty, after which it begins to atrophy. ...

Local chemical messengers, not generally considered part of the endocrine system,include autocrines, which act on the cells that secrete them, and paracrines, which act on a different cell type nearby.Contents [hide]∙ 1 Chemistry ∙ 2 Target cell specificity ∙ 3 Interaction of ...
In the majority of reported cases, parotid gland aplasia is seen with craniofacial abnormalities or hypoplasia of other ectodermal structures, particularly the lacrimal glands. We present a 14-year-old male with bilateral parotid gland aplasia detected incidentally on MRI of the brain and then ...
“fight or flight” response. When your brain senses danger, it produces adrenaline that encourages your body to make changes like dilating your pupils, increasing your blood flow, and breathing faster. Adrenaline also has many uses in medicine. It can be used to open the airways ofasthma...
Lithium amplifies agonist-dependent phosphatidylinositol responses in brain and salivary glands 1. The effect of Li+ on the agonist-dependent metabolism of [3H]inositol has been studied in rat brain, rat parotid and the insect salivary gland. 2. When ......
The vibrations from the middle ear change into nerve signals in the inner ear. The inner ear includes the cochlea(耳蜗)and the semicircular canals. The snail-shaped cochlea changes the vibrations from the middle ear into nerve signals. These signals travel to the brain alo...

Functional Capacity of Solid Tissue Transplants in the Brain: Evidence for Immunological Privilege The capacity of the mammalian brain to support the physiological function of allografts was assessed in parathyroidectomized Fischer strain rats bearing ei...

Subsequently, the midgut, hypopharyngeal glands, and brain were analyzed in light and transmission electron microscopies. The midgut was not affected after exposure, except in the posterior region with cell fragments in the lumen and changes in the mitochondria. The hypopharyngeal glands were severely...
