Olfactory system

Humans have five basic senses: hearing, vision, smell, taste, and touch. The definition of a “sense” is “any system that consists of a group of sensory cell types that respond to a specific physical phenomenon and corresponds to a particular group of regions within the brain where the signals are received and interpreted.” In this paper I will be taking about sensory deprivation which is the lessening or complete loss of senses. I will discuss what hearing, vision, smell, taste, and touch is and…

What are the primary functions of the respiratory system? The human respiratory system is made up of several organs (nose, pharynx, larynx, trachea, bronchi, and lungs). They are responsible in receiving oxygen and expelling carbon dioxide. However, the exchange of gases takes place in the lungs making them an important organ of the breathing process. RBC’s gather oxygen from the lungs transferring it to other parts of the body. During this process the RBC’s gather carbon dioxide and transfers…

Senses are a vital necessity in human life. Senses consist of sight, sounds, smell, tastes, and texture. A main function of the senses is to maintain homeostasis. There are two senses; general and special. “General senses are those with receptors widely distributed throughout the body, including skin, various organs and joints” ( ,Pg. 444). “Special senses have more specialized receptors and are confined to structure in the head, such as eyes and ears”( ,Pg.444). Over time, scientists…

our understanding of neurological sciences has vastly improved alongside the examination and research of C. elegans. Through their ease of accessibility, C. elegans, have become a staple organism in discovering the mechanisms in which the nervous system promotes survival (Allen et al. 2015). The C. elegans’ structural integral is very straightforward, consisting of 302 neurons, with 60 of them being sensory neurons (Pieczynski 2016). Thanks to this simplicity, we can easily observe C. elegans’…

between air and blood in the lungs and internal has exchange between the blood and body tissues. Cellular respiration is a chemical reaction inside the mitochondria of cells in and cellular metabolism is converting energy in food to become ATP. 2. The olfactory mucosa is the lines of the roof in the nasal cavity. The respiratory mucosa is lining the rest of the nasal cavity and it’s important for defense. It contains mucus for trapping inhaled particles, mucus is pushing towards pharynx and…

emotional memory learning. After that, two specific systems – norepinephrine (NE) projections from locus coeruleus (LC) and serotonin (5-HT) projections from dorsal raphe nuclei (DR) – and its effects on threat learning and fear conditioning will be discussed. Locus Coeruleus and its projections to other regions involved in threat learning The locus coeruleus (LC) is the largest nucleus of noradrenergic neurons in the central nervous system and is located in the pons. The excitation of…

because of its endoskeleton, and their nerve cord that runs along the spinal cord and connects to their brains. This means that they have a central and peripheral nervous system. Back to their brains, they’re divided into three parts, the fore-brain, mid-brain and hind-brain. The fore-brain controls the frogs sense of smell (the Olfactory lobe), along with the cerebral hemispheres, and diencephalon. The mid-brain controls its vision (Optic lobes) and the hind-brain controls all the automatic…

LIMBIC SYSTEM AND TINNITUS Introduction A human body is a very delicate and complicated group of systems and organs that work together. We can say that each part of the body is controlled by and connected to several many organs. Thus, many diseases and disorders in one organ can actually indicate the error in completely different organ or system. That brings us to this, The limbic system and Tinnitus. A person who has tinnitus is a person who is continuously hear noisy and annoying voices and…

hearing (audition), vision, and touch. (somatosensation). Our senses help us navigate in the world and provide data for perception. Sensation is how the body brings information from the outside world into the brain. The vision system is the sense that allows…

Parkinson's: Sniff test could predict risk up to a decade earlier Parkinson's is known as a disorder that affects the central nervous system that affects movement. The estimated number of people who are living with Parkinson's disease is around 10 million people and 10% of that population lives in the United States. A study back in 2011,"Olfactory loss in Parkinson's Disease", talks about how when the elderly lose their sense of smell it could be an early indicator on if they are developing…
