P1 [pic] Cell membrane - encloses the contents of the cell and regulates the flow of substances into and out of the cell. Mitochondrion - this feature produces a substance called adenosine triphosphate (ATP) which is the carrier of energy in all cells. Centriole - these two features made of hollow tubules play a key role in cell division. Ribosomes - these small‚ granular features of the cell play a key role in the assembly of proteins. Chromosome - During cell division‚ DNA‚ the

Emily Muñoz 1/7 period Nervous System The nervous system consist of all the nerves the body has. Controlling not only the actions the body takes but the emotions a human being feels. The spinal cord‚ brain‚ and many nerves revolve around the nervous system. There are three overlapping functions that use millions of sensory receptors‚ that monitor the body. By monitoring the body the functions detect any changes the human body has had.Two components separate the nervous system allowing us to focus

It is amazing how some systems in our body works together in situations to help us to have the ability to react and be alert of our surroundings such as being in danger or suffering from stress which is an important factor of many health problems. The two systems that I am referring to are the endocrine and nervous systems. they help to regulate our bodies back to our normal state to help to maintain healthy functioning. There are two systems that work with one another to signal the brain when something

Cell Membrane Structure Phospholipids are arranged in to layers‚ called the bilayer. They only have 2 fatty acids‚ this is because the third fatty acid is replaced by a negatively charged phosphate group. The phosphate heads are polar‚ in other words attracted to water‚ therefore they are hydrophilic. The lipid tails are non-popular as they’re not attracted to water and therefore known as hydrophobic. When phospholipids are added to the water‚ they rearrange themselves so that the hydrophilic heads

Brain Structures and Functions Viviana N. Reyes ESE370: Learning & the Brain (CXI1409A) Instructor: Charisse Jones March 9‚ 2014 Brain Structures and Functions Many are fascinated by the brain and its functions. Our brain is composed of different units and lobes that work together but each part‚ of course‚ has a special function. We all ask ourselves‚ how is it that we learn? Do our senses have anything to do with getting new information into our brain? Technology

The skeletal system: The bones of the skeletal system hold the body together‚ give it shape and support weight. They also enable the body to move and provide protection to the vital organs. There are four types of bones found in the human body: they are long bones which can be found in the arms‚ legs‚ fingers and toes‚ short bones which are found in the wrist and ankles‚ flat bones such as those in the skull‚ thorax and pelvis‚ irregular bones such as the bones of the vertebral column and face

Endocrine Vs Nervous System The endocrine system acts with nervous system to coordinate the body’s activities. Both systems enable cells to communicate with others by using chemical messengers. The endocrine system uses chemical messengers called hormones that are transported by the circulatory system (blood). They act on target cells that may be anywhere in the body. The endocrine system is slower than the nervous system because hormones must travel through the circulatory system to reach their

The nervous system is made up of millions of neurons and interconnected nerves that are comparable to a wiring system. The nervous system is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The nervous system functions like a corporate giant. The CEO is the leader in the CNS and the officers and delegates are the PNS. The CNS gives the commands and the PNS follows the commands. The Central Nervous System The central nervous system (CNS) is
