It is accompanied by a wide range of physiological changes (Swencionis‚ 162). During vigorous laughter the body brings in extra oxygen‚ shudders the internal organs‚ causes muscles to contract‚ and activates the hypothalamus‚ pituitary‚ and adrenal glands. This results in an increase in the secretion of endorphins (internally produced morphine-like molecules). This "internal jogging" produces an increase in oxygen absorption‚ increase in heart rate‚ relaxation of the muscles‚ and increases in the number

the calyces. (Fig. 27). They are about 27 in the human kidney and owe their name to Marcello Malpighi‚ an Italian physician of the seventeenth century who dedicated time to microscopic anatomy and histology. Eyebrows‚ eyelids‚ lacrimal glands‚ salivary glands‚ nails‚ turbinates of the nose‚ intrinsic factor of Castle‚ and pyramids of Malpighi represent a few of those feeble‚ insignificant parts of the body which function as well as the noble organs reported

transversely by commissures. Different groups of arthropods exhibit different degrees of fusion of the ganglia. In insects the first ganglion‚ the subesophageal‚ is formed by fusion of three pairs of ganglia; it sends nerves to the mouthparts and to the salivary glands. The segmental ganglia in the thorax and abdomen provide nerves to the appendages‚ dorsal muscles‚ sense organs‚ and heart. Insects have 3 pairs of thoracic ganglia and up to 10 abdominal ganglia. The most common sensory receptors in arthropods

Kayla Berezne Mrs. Cohen Honors Biology 24 March 2013 Genetic Predictions in the Fruit Fly The Drosophila melanogaster is a fruit fly with a very short life cycle. They can be winged or wingless‚ and have red eyes or white eyes. The different options are called alleles. Alleles are the variants of a specific gene‚ and one is received from each parent on each chromosome. (“What Are Dominant and Recessive?”). It was chosen to use winged females and wingless males to predict the offspring in this

The monogastric digestive tract is quite similar to the ruminant digestive tract‚ in the way they have many of the same parts and they process the food similarly. The mouth‚ oesophagus‚ liver‚ pancreas‚ gall bladder‚ small intestine‚ and large intestine in a ruminant species have similar functions to monogastric species. Both the digestive tracts start with the mouth‚ and although they are formed differently in order to eat the different diets‚ both the mouths are used to grab‚ chew and push the

A bumblebee is any member of the bee genus Bombus‚ in the family Apidae. There are over 250 known species‚[1] existing primarily in the Northern Hemisphere although they also occur in South America. They have been introduced to New Zealand and the Australian state of Tasmania. Bumblebees are social insects that are characterised by black and yellow body hairs‚ often in bands. However‚ some species have orange or red on their bodies‚ or may be entirely black.[2] Another obvious (but not unique) characteristic
