As with the male counterpart, the ovaries are derived from the genital ridge later descending to their final position in the pelvis. In adults, the ovaries have an ovoid shape and are usually 3-5cm long. They are a layered structure with an outer layer germinal epithelium, tunica albuginea, cortex and medulla that is innermost (fig. 1). Although now challenged by recent discoveries (1), the germinal epithelium; a continuation of the peritoneum, is inaptly named due the mistaken belief that germ…

Hersheypark inside the water park. The roller coaster, is filled with many twists, turns, and loops. This roller coaster is not just any roller coaster, it has a fabulous view of the whole park. The tallest point on this ride, where you feel the highest potential energy, is over 4,586 feet tall. This ride is over four football fields long!! While you are waiting in line you can see that the cars have three rows and in each row there are eight seats. The coaster cars you see as the buckles come…

At the spinal level, the PNS and CNS are bilaterally symmetrical. And studies have shown that the two sides of the spinal cord are not independent due to the findings that unilateral peripheral nociception results in contralateral responses (Koltzeburg, 1999). The contralateral pain was perceived at a lesser magnitude and has a delayed response. This contralateral pain phenomenon can be attributed to a similar pathway as central sensitization leading to secondary hyperalgesia. Primary…

Roller coasters with loop-the-loops are generally rides that appeal to thrill seekers, however without the use of dynamics, these rides would not be able to function. A roller coaster loop-the-loop is a type of large scale centrifuge, as one approaches the loop, the rider's inertial velocity is straight ahead. However the track of the roller coaster keeps the car and therefore the rider, from travelling in a straight path. The force of a rider's acceleration pushes them from…

https://www.youtube.com/watch?v=NcmF5lDL8MM Have you ever been to an amusement park and wondered how a rollercoaster goes around the loop of the track? Well I sure have, this is all due to centripetal force. This is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. The curves of these loops on rollercoasters resemble the curves of a circle. The coaster is continuously changing its direction while…

different parts of the cells. The neuron sends the signal that the mother has disappeared from the soma down the axon. The axon then sends the impulse out the axon terminals through the synapses, the space between neurons. The impulse gets released as a chemical substance, called a neurotransmitter, through the synapse and the receiving neuron gets the signal through the dendrites. When the brain finally receives the impulse to the right part of the brain, it realizes that mom is gone and starts…

Regulatory Behavior Paper The nervous system is in charge of receiving and relaying the information that is collected; it is also in charge of monitoring and responding to both the internal and the external changes that help to control and coordinate the body’s functions. The sensory stimuli is able to become more apparent with the help of a strong and productive nervous system; this would include any change in emotion, memory or the environment. Neurons are known as the messengers of the body.…

One of the major channels of the spinal cord is the spinothalamic tract; a sensory pathway. It conveys nerve impulses for sensing pain, warmth, coolness, itching, tickling, deep pressure, and crude touch. (Tortora, 2014-01-22, p. 461). Based on that description and as the name implies, information will travel from the region of stimulation on the skin to the CNS, ultimately landing at its destination at the thalamus; thus, making it an ascending pathway. This pathway is further divided into…

This investigation focusses on an egg falling off a height of 4 metres in the fastest possible time without breaking the egg. In order to make this happen, an investigation must be conducted on the forces acting upon gravity, crumple zone theory, and energy transfer and absorption. The world is made up of matter and energy (Cool Cosmos, 2015). Matter is made up of atoms and molecules and these atoms and molecules are always in constant motion because of energy (Cool Cosmos, 2015). Gravity is…

A. SIGNIFICANCE: Lack of knowledge of the key molecular players and signaling pathways is a critical barrier to the progress of understanding the role of new protein synthesis in specific components of neural circuitry for establishing long-term memories. The proposed project addresses this important problem by employing a multidisciplinary approach in which we systematically combine tools of imaging, state of the art genomics and bioinformatics, molecular biology, functional analysis and…
