Your brain and your spinal cord are apart of this and that also happens to be the definition of the system. With your brain, there are three sections of it. You have the hindbrain which is the part of the brain that contains the medulla, pons, and cerebellum and it is responsible for keeping our body operating. The next section is the midbrain and it is the connection between the hindbrain and forebrain. It is the center for the eyes and ears and reticular formation is the main key here.
Hind brain (Rhombincephalan) the hind brain contain the brain stem and the medulla oblongata (Myelencephalon) form by the anterior thickening of basal plate and posterior alar plate separated by sulcus in the fourth ventricle. The hind brain continues to form the spinal cord. As like cerebrum, cerebellum has fissured mass in the posterior cranial fossa attached with brain stem by three pairs of peduncles. From the base of the brain stem the 12 pairs of cranial nerves are arising. The motor nuclei of the IX, X, XI and XII cranial nerves line in the fourth ventricle is formed by the basal plate neurons.
To better understand Biopsychology, one has to learn about the three most crucial parts, which are the brain, neurotransmitters, and the nervous system. The brain is in-charge for the cognition, senses, motor abilities, and feelings through its’ four lobes of the
The ventral ramus is the most prominent and most important branch and it supplies the structures ventral to the neural canal. Second branch is the sinuvertebral nerve is a small branch arising from the ventral ramus traverses medially over the posterior aspect of the disc, vertebral body and posterior longitudinal ligament and supplies these structures. Third branch, the dorsal ramus courses dorsally and pierces the intertransverse ligament near the pars interarticularis and divides into 3 branches which supply the structures dorsal to the neural canal. The lateral and intermediate branches supply the posterior musculature and skin while the medial branch divides into 3 branches and supplies the facet joints at and the adjacent
Their journey is comprised of being transmitted through the spinal cord, past the medulla where they cross, through the thalamus, and finally to the parietal lobes, specifically the postcentral gyrus. Here, in the postcentral gyrus, the somatosensory cortex is located. Divided into primary and secondary, the somatosensory cortex houses neuron designated to specific locations of the body that they are responsible for detecting sensations
The nerve involves in the transmission of electrical signals from the various parts of eye to CNS (brain), then the brain send an appropriate response in the form of an image to see (the objects what we see around us). The defects in the cranial nerve (optic nerve) such as inflammation (neuritis) can cause the alterations in normal vision and sometimes even cause
1. What is Cognitive psychology? the study of mental processes such as attention, language use, memory, perception, problem solving, and thinking. 2. What are the three major processes involved in Memory?
The sound waves are translated to fluid waves in the cochlea that are then sensed by nerves connected to fine hairs that float in the fluid and is then sent on to the brain for interpretation. This is the area that a human “cochlear implant” stimulates to help correct hearing loss. The feline cochlea has 3 complete turns while the human cochlea only has 2.75 turns. They have 10,000 more auditory nerves than humans. Near the cochlea is another fluid- and carbonate crystal-filled structure called the vestibular apparatus that is in charge of balance (Bailey, 2013).
We have been used to living with perception so we molded our living around our senses and most of the knowledge we acquire is through them. However there are certain flaws to it, such as optical illusions and background that influences our perception, that makes us question how accurate our way of seeing the world is. Overall, sense perception is a good way of knowing if shared with other people so, with all the different perceptions of the world due to different life experiences, it all can be combined in a greater a more accurate perception of
INTRODUCTION Anatomy and Physiology of Angiocentic Glioma The most complex part of the body is the brain. It controls muscles movement, behavior, senses and all other functions of the body. The gray matter or cerebral cortex in the brain is the place where all the information is processed. Meanwhile, the cerebral lobe is the main source of intellectual activities. The nerve fibers in the two hemisphere of the cerebral lobe cross over and causing the right side of the cerebrum to control left side of the body and left side of the cerebrum to control right side of the body.
