Cold Blooded and warm Blooded Animals

Cold Blooded and warm Blooded


Cold Blooded and Warm Blooded animals

Cold Blooded 



Cold blooded

          Cold Blooded do not regulate their internal body temperature they change their temperature to the change in outer environment's temperature.
The process to maintain the temperature is called thermal homeostasis.
The process of maintaining this temperature is called thermal homeostasis.
They need less energy for maintaining their body temperature,so they need less amount of food.
They produce resistivity against  microorganisms invading their body for causing disease,if happens,they lower the effect of infection by decreasing the body's temperature.
Hibernation-
Resting stage at the time of winters which can be for weeks or months.
Aestivation
Resting stage at the time of summer.
The temperature of a body depends on the temperature of the external environment.

Metabolic rates changes with the change in environment's temperature.
Cold blooded are categorized in three types:

Ectothermy:
Body temperature is maintained according to the temperature of the external environment, it means if there is sunlight, they will maintain their temperature accordingly and at night that is at the time of moonlight, their body will change their internal temperature again and becomes cool. Examples reptiles.

Poikilothermy:
 The temperature of which fluctuate with the variation in temperature of the encompassing medium. Examples are frogs, turtles.

Bradymetabolism:
This type depends on the speed of metabolism, one’s body perform. An example is insect

Warm Blooded Animals

Warm blooded



These aninals obtain their body heat from metabolic process.
They continuously produce internal heat. They have a large amount of fat. they maintain a high core temperature,due to it the the biochemical process and nervous system functions normally even at higher external temperature.
These animals can survive in those habitats where ectotherms can not live.

Endothermy: 
      Body maintains its temperature by an enclosed means like sweating, shivering, etc,An example could be a dog. 
Homeothermy: 
   Body regulates its required internal temperature regardless of the external temperature, rather body tends to take care of the upper temperature than surrounding,An example is human. 
Tachymetabolism: 
High metabolism rate could be a result of temperature,an example is bird.

Neurotransmitters and receptors

Image
Neurotransmitters and receptors Did you know there are billions of neurons—and trillions of synapses—in your amazing brain? ^1 1 start superscript, 1, end superscript  (No wonder you can learn anything, including neurobiology!) Most of your synapses are  chemical synapses , meaning that information is carried by chemical messengers from one neuron to the next. In the article on synapses, we discussed how synaptic transmission works. Here, we’ll focus on  neurotransmitters , the chemical messengers released from neurons at synapses so that they can “talk” to neighboring cells. We’ll also look at the receptor proteins that let the target cell “hear” the message. Neurotransmitters: Conventional and unconventional There are many different kinds of neurotransmitters, and new ones are still being discovered! Over the years, the very idea of what makes something a neurotransmitter has changed and broadened. Because the definition has expanded, so...

The Importance of Animal Physiology

The Importance of  Animal Physiology Why is the study of animal physiology important to you and to people in general? Not the least of the reasons is the one we have already emphasized—namely, that a full understanding and appreciation of all the marvels and other phenomena of the animal world depends on an analysis of how animals work. The study of physiology draws us beyond surface impressions into the inner workings of animals, and nearly always this venture is not only a voyage of discovery, but also one of revelation. The study of physiology also has enormous practical applications because physiology is a principal discipline in the understanding of health and disease. The analysis of many human diseases—ranging from aching joints to heart failure—depends on understanding how the “human machine” works. A physician who studies heart disease, for instance, needs to know the forces that make blood flow into the heart chambers between one heartbeat and the next. The physician ...

What are chromosomes?

Image
Chromosome Chromosome During cell division the chromatin material change into thread like structure called chromosome. Chromosomes are also called physical basis of hereditary. On the chromosomes small bodies are located call genes. There are thousands of genes are present in an organisms.Genes are the unit of heredity. These genes contain hereditary character which are transfered from one generation to another by the help of chromosomes. Chromosomes were discovered by a biologist waldyer in 1876. After that in  1908 Sutton identified the function of chromosomes,that they take part in the transfer of hereditary characters.      ( Next post will be about Structure of chromosomes)
