Writing Assignment #2 #1- Sleep deprivation is a common problem in modern society. Sleep plays a crucial role in optimal health and wellness throughout a person’s life. Getting a proper amount of sleep can help aid in mental and physical health. Sleep deprivation can occur from various causes. Often the stresses and vigor of daily life may intrude upon our ability to sleep well. In any case‚ sleep deprivation is not only detrimental to one’s well being‚ but it can also impair cognitive ability and

It is caused by the body attacking its own tissues as well as allergies‚ bacteria‚ viruses‚ and other genetic factors. 2) When the triceps brachii muscle contracts‚ what movements does it produce? When the triceps brachii muscle contracts‚ it produces extension of the arm. 3) Why is the inferior region of the shoulder joint most vulnerable to dislocation? It is most

consists of many areas that all work together in unison in order for the body to perform the tasks it is told to perform. The brain is responsible for controlling both voluntary and involuntary actions and coordinates and controls other organs in the body. The brain can do this by the use of postsynaptic potentials‚ synaptic transmission‚ and receptors that are responsible for producing and regulating specific behaviors. There are also six primary neurotransmitters that play a large role in how an individual

in Biology. Cycles can be seen even at a molecular level in the body. An example of this would include the passage of action potentials down neurones in the nervous system. When the cell membrane is at its resting potential‚ the sodium potassium pump is turned off. When a stimulus is applied to a neurone‚ the resting potential is (-70mV) is reversed – this is the action potential (depolarisation). The energy of the stimulus causes the intrinsic sodium voltage-gated channels to open‚ allowing sodium

Nervous System II: Anatomy Review 1. The somatic nervous system stimulates ____________ muscle. The autonomic nervous system stimulates ___________ muscle‚ ____________ muscle‚ and ___________. 2. The autonomic nervous system (ANS) consists of two divisions‚ each innervating the effector organs. The sympathetic nervous system (SNS) generally speeds up everything except digestion. The parasympathetic nervous system (PNS) generally slows down everything but digestion.

Chapter 2- Darwin was the first to suggest how evolutionoccurs. Humans belong to the primate family known as hominins. Characteristics that evolved to perform one function but were co-opted to perform another function are called exaptations. Each group of three consecutive nucleotide bases along the strand of messenger RNA is called a codon‚ which instructs the ribosome to add amino acids to the protein being constructed. Subsequent to the nature-nuture issue‚ a second line of thought surrounding
