FUNCTION OF FOURBRAIN

i.  The forebrain plays an important role in processing of information related to cognitive activities, sensory and associative functions and voluntary motor activities. 
ii.  Parts of forebrain and their function:
a. Cerebrum: Sensory integration, control voluntary movements, speech and abstract thoughts 
b.  Thalamus: Relay centre between medulla and the cerebrum 
c. Hypothalamus

The hypothalamus, a vital part of the brain, performs various essential functions, including:

1. Regulation of Temperature: The hypothalamus helps maintain your body's core temperature by triggering responses like sweating or shivering.

2. Control of Hunger and Thirst: It regulates feelings of hunger and thirst, influencing your eating and drinking behavior.

3. Sleep Regulation: The hypothalamus helps establish sleep-wake cycles and plays a role in the sleep patterns and circadian rhythms.

4. Emotional and Behavioral Responses: It is involved in emotional responses, motivation, and behavioral patterns.

5. Hormone Regulation: The hypothalamus controls the pituitary gland, which, in turn, regulates the release of hormones that control various bodily functions, such as growth, stress response, and reproductive functions.

6. Autonomic Nervous System Control: It influences the autonomic nervous system, which controls involuntary functions like heart rate, digestion, and respiratory rate.

7. Thirst and Water Balance: The hypothalamus monitors blood composition and triggers thirst and the release of antidiuretic hormone (ADH) to maintain water balance.

8. Regulation of Stress Responses: It plays a role in the body's response to stress, including the release of stress hormones like cortisol.

9. Control of Circadian Rhythms: The hypothalamus helps regulate the body's internal clock, which affects sleep-wake cycles and daily rhythms.

10. Sexual Behavior and Reproduction: It influences sexual behavior and reproductive processes by regulating the release of hormones like gonadotropin-releasing hormone (GnRH).

These functions collectively make the hypothalamus a critical regulator of many physiological and behavioral processes in the body.

Structure of myosin & actin filaments.

Image
i. Myosin filament: a. Each myosin filament is a polymerized protein. Many meromyosins (monomeric proteins) i constitute one thick filament. b. Myosin molecule consists of two heavy chains (heavy meromyosin / HMM) coiled around each other forming a double helix. One end of each of these chains is projected outwardly is known as cross bridge . This end folds to form a globular protein mass called myosin head . c. Two light chains are associated with each head forming 4 light chains/light meromyosin / LMM. d. Myosin head has a special ATPase activity . It can split ATP to produce energy. e. Myosin contributes 55% of muscle proteins. f. In sarcomere, myosin tails are arranged to point towards the centre of the sarcomere and the heads point to the sides of the myofilament band. ii. Actin filament : It is a complex type of contractile protein. It is made up of three components: a. F actin : It forms the backbone of actin filament. F actin is made up of two helica

Table of content:  1. Plants 2. Animals 3. Humans 4.  Gods Plant Plants   are the   eukaryotes   that form the   kingdom   Plantae ; they are predominantly   photosynthetic . This means that they obtain their energy from   sunlight , using   chloroplasts   derived from   endosymbiosis   with   cyanobacteria   to produce   sugars   from   carbon dioxide   and water, using the green pigment   chlorophyll . Exceptions are   parasitic plants   that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Animal Historically, as in  Aristotle's biology , the plant kingdom encompassed all living things that were not  animals , and included  algae  and  fungi . Definitions have narrowed since then; current definitions exclude the fungi and some of the algae. By the definition used in this article, plants form the  clade   Viridiplantae  (green plants), which consists of the  green algae  and the  embryophytes  or land plants ( hornworts ,
