Anatomy: Special Senses

Prompt 1

The human body has two senses types: special and general. Special senses include various body organs to feel the surroundings, for example, balancing, seeing, tasting, and smell, whereas general senses are only related to touch (Miller, 2020). The sensory data that the brain receives is collected by the skin that touches the objects. The general senses encompass pain, pressure, vibration, and proprioception. For instance, if we touch a hot cup of coffee, the fingers suddenly know that they would be burnt, and they immediately try to retract themselves from the cup. This is the information processing that the brain acts in a certain way when the skin touches the cup and gets the stimulus. The brain formulates the important functions when the sense of touch gathers the prompts from the skin. Sensory receptors play a key role in this entire processing.

Prompt 2

The structure of olfaction involves the nose and nasal cavities that help in smelling along with the upper parts of the olfactory system with mucous. The lower parts assist in clarifying the passages for respiration. The function of the olfactory system is to detect and identify different smells that are present in the air in the form of molecules (Bailey, 2021). The function of the olfactory bulb is to process the information for smell for the brain that comes from olfactory receptors. The bony structure of the nose help in keeping the entire framework intact and keep it in shape.

Moreover, the olfactory nerve is the primary nerve involved in the whole process. It is the sensory reception nerve that enables smelling. It is carried from a special afferent nerve within the nose and has a particular connection with the thalamus (Physiopedia, n.a.). It ends at the olfactory bulb, and the transmission of impulses caught from the stimuli within the air reaches the cerebral cortex.

Menopause: A Short History From Human Anatomy and Physiology, Spence and Mason, 2nd Edition from 1983, comes this description of Menopause. At about age 50, the ovarian and menstrual cycles gradually become irregular. Ovulation fails to occur during many of the irregular cycles and in most women the cycles cease altogether over the next several months or at most, a few years. The cessation of the menstrual cycle is referred to as

Anatomy Major cavities of the body and their organs: Our body is made up of solid structures and many cavities. The organs are packed in these cavities and they fill these cavities. The major cavities in our body are: the ventral cavity, which is surrounded by the rib cage and the abdominal musculature and dorsal cavity, which is surrounded by the bones of the skull and vertebral column.

). These complications will be discussed in the discussion section of this paper. Discussion Taking into account the physiological functioning of these bacteria on the human sensory and muscles muscle system it becomes clear that that this can be a serious threat to human health and, as discussed above, this disease can lead to death. Modern medicine has however created an antidote to the effects of this disease. Tetanus can be prevented

Human-Equipment Interface Technological transformations have brought widespread use of machines and tools to the work setting. Owing to this, such concepts as human-machine/equipment interfaces have become increasingly prominent. In its simplest form, human-machine interface (HMI) refers to the point or extent of interaction between a machine and its operator; taken literally, it is the area of the machine and that of the human that interact during the execution of a task.
