The osteocytes maintain communication with each other and likely played the role in sensing the areas that need to be remodelled, transmitting information to other cells, and initiating the bone-remodelling process. However, as we age daily remodelling
(say: puh-TOO-uh-ter-ee) gland hypothalamus (say: hy-po-THAL-uh-mus) The Biggest Part: the Cerebrum Brain CerebrumThe biggest part of the brain is the cerebrum. The cerebrum makes up 85% of the brain 's weight, and it 's easy to see why. The cerebrum is the thinking part of the brain and it controls your voluntary muscles — the ones that move when you want them to. So you can 't

Introduction The brain is known by many individuals as the most important organ in the human body. This is that the brain controls many functions of the body individuals use daily throughout the course of their lives. According to Brain Anatomy (2016) “The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings (para. 1).”
Personality traits are polygenic and thus, a combination of many genes determines the personality of an individual. This shows that genes play a crucial role in influencing one’s personality and behavior although environmental factors are also important in shaping one’s behavior. Biological Psychology—Hindbrain The hindbrain is the “oldest brain region” (Feist et al., 2015). Hindbrain is located on bottom end of brain and thus, it is directly attached to the spinal cord.
The body is composed of primary networks that perform as one that sustain a body to function properly such as central nervous system, circulatory system, digestive system, musculoskeletal system, and respiratory system. The central nervous system maintains the body and brain activity it is composed of two sections the brain and the spinal cord this system executes multiple functions that regulate voluntary and involuntary operations such as speech, walking, blinking and breathing these senses are stimulated by the system of neurons, neurons are cells within the nervous system. Neurons consists of four major sections such as a cell body, an axon, dendrites, and synaptic terminal. The purpose of neurons is receiving incoming information and communicating
The brain and nervous system are able to control both the heart rate and blood pressure due to the two carotid sinuses, that are located in the right and left carotids, and the aortic arch. The nerve endings on the outer layer of both the carotid sinuses and the aortic arch form two different nerves, which are known as baroreceptors. Baroreceptors, or receptors for pressure, send information concerning what is happening in blood vessels, particularly about stretch. The more pressure in blood vessels, the more they stretch. These pressure receivers send multiple signals to the Medulla oblongata and brainstem.
Is technology changing our brains for the better or for the worse? The human brain is a biological masterpiece and is the most advanced organ on the face of the planet. In Richard Restak’s essay “Attention Deficit: The Brain Syndrome of Our Era,” he speaks about how the advancements in technology in this modern era have affected the brain’s habits and functions. Multitasking is requiring the brain to change how it functions, its organizations, and efficiency throughout day-to-day tasks and is also enabling people to do things otherwise not possible. Within the past two decades, the amount of time we spend on using technology has increased by a large amount.
The nervous system has many significant functions such as direction of your movements, focusing of the eyes, pain sensory, contraction of the muscles allowing your heart to pump sending blood and oxygen to all your vital organs and removing harmful toxins. Your brain is the control centre of the body. The most largest and complex part of the brain is the cerebrum, the centre of learning. This controls the way you use language, feel emotions and think. It is divided into two sides which are connected together by nerve bundles called the corpus callosum.
The PNS contains somatic nervous system and the autonomic nervous system. The autonomic nervous system controls the function of internal organs like your heart, stomach, cardiac muscle, and your glands. The autonomic nervous system has an effect on the organs, muscles, and glands are all done voluntary. The autonomic nervous system can change the body temperture, send extra blood to a particular area, slow your heartbeat, and pull the stomach secretion. The somatic nervous system is made up of sensory organs and nerves that connects to the skin, also that connects to all the skeleton muscles.
The medulla oblongata is located between the pons and spinal cord. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. The midbrain is involved in functions such as vision, hearing, eye movement, and body movement. The pons are involved in motor control and sensory analysis. For example, information from the ear first enters the brain in the pons.
Nonetheless, our group observed specific locations in the skull that over time, changed among species. The following methodology will include how to observe or examine the different locations that were relevant to the study. By looking for the widest part in the back of the skull the location of the maximum skull breath can be identified. The degree of postorbital constriction can be recognized by observing the space behind the brow/supraorbital ridge. The zygomatic flare can be examined by evaluating how wide is the zygomatic bone.
3. The calcium levels in the blood and bones are being controlled and regulated by the parathyroid glands. Parathyroid glands are next to and sometimes inside the thyroid glands. Parathyroid glands are small glands in the endocrine system that control how much calcium is inside our bones, which affects how much calcium is in our blood. Calcium control is important because it lets the normal conduction of electric currents to run in our nerves and is also, the main element that causes our muscles to contract.
