BRAIN STRUCTURE AND FUNCTION

The BRAIN is made of three main parts : 
  • Forebrain
  • Midbrain
  • Hindbrain
The forebrain consists of the cerebrum, thalamus, and hypothalamus ( part of the limbic system). The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons, and

medulla. often the midbrain, pons, and medulla are referred to together as the brainstem.

What do each of these lobes do?
  • Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving
  • Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli
  • Occipital Lobe- associated with visual processing
  • Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech
  • The cerebellum, or "little brain", is similar to the cerebrum in that it has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance.
  • The cerebellum is assumed to be much older than the cerebrum, evolutionarily. What do I mean by this? In other words, animals which scientists assume to have evolved prior to humans, for example reptiles, do have developed cerebellums. However, reptiles do not have neocortex. 


  • The limbic system, often referred to as the "emotional brain", is found buried within the cerebrum. Like the cerebellum, evolutionarily the structure is rather old.
  • This system contains the thalamus, hypothalamus, amygdala, and hippocampus. 
Brain Stem: 


  • Underneath the limbic system is the brain stem. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. Scientists say that this is the "simplest" part of human brains because animals' entire brains, such as reptiles (who appear early on the evolutionary scale) resemble our brain stem

    I read the full post about brain structure and function i feel that the information is very nicely represented and another special fact is that very easy to read no complicated part as you know @ brain is the most complicated part of human body !!!
    more intresting facts about your brain

PERBEZAAN ANTARA LATIHAN AEROBIK DAN LATIHAN ANAEROBIK

PERBEZAAN ANTARA LATIHAN AEROBIK DAN LATIHAN ANAEROBIK Terdapat dua jenis latihan utama iaitu: Latihan anaerobik  Latihan aerobik ANAEROBIK bermaksud aktiviti yang tidak memerlukan penggunaan oksigen dalamproses penghasilan tenaga.  Latihan anaerobik merupakan latihan berintensiti tinggi dalam tempoh masa yang singkat yang menyebabkan berlakunya metabolisma anaerobik.Latihan jenis ini biasanya digunakan oleh atlet dalam sukan yang melibatkantempoh yang singkat. Latihan anaerobik tidak melibatkan penggunaan oksigenbagi menghasilkan tenaga. Terdapat dua jenis metabolism yang digunakanuntuk menghasilkan tenaga yang digunakan dalam latihan anaerobik iaitu sistem ATP-PC dan Glikolisis. Beberapa contoh aktiviti anaerobik seperti : Larian 100m Bola keranjang Angkat berat  Berenang 100m untuk meningkatkan kekuatan,kelajuan dan kuasa serta saiz otot berdasarkan keperluan sesuatu sukan tersebut. Contoh latihan anaerobik yang digunakan untuk meningkatkan keu...

WHAT IS COORDINATION SYSTEM??

Image
T he definition of coordination system is work together to process information received from stimuli and to produce appropriate responses. We have two coordination systems one is the nervous system and other one is endocrine system. The nervous system are regulates the body’s activities and responses. It works by means of specialized cells called neurons which transmit information in the form of nerve impulses. Besides that, the endocrine system regulates and coordinates the body functions by means of chemical substances called hormones. The endocrine system regulates functions which require maintained responses. These include changes during the metamorphosis of some animals, growth, and the production of milk in mammals. Now, we talk about the responsive organs for coordination. There are two types of responses to stimuli, one is motor responses, the response is movement and endocrine responses, the response is the release of hormones. The responsive organs, or effectors, control mot...
