Human Science – CHAPTER 1 1. Which Organ system maintains a relatively slow-acting degree of control over most bodily functions? Endocrine System (hormones act in minutes to hours‚ in contrast to nerve impulses‚ which act in fractions of a second). 2. The esophagus and the trachea run side-by-side through the thorax. In which systems are these organs found? The esophagus belongs to the digestive system‚ and the trachea belongs to the respiratory system. (The esophagus carries food to the stomach

We are able to visualize‚ feel‚ smell‚ and hear the world around us due to a system called the sensory system. All around the surface of our body we have detectors that are known as receptors. These receptors‚ in the form of cells‚ are specialized to capture specific forms of energy- whether heat‚ light‚ chemical‚ or mechanical (1). The environmental cues that are detected by our receptors on the surface of our body are then transformed into electrical signals‚ or nerve impulses‚ that can be sent

Answers a. gap junctions: really fast‚ nondirectional‚ part of nervous system b. neurotransmitters: fast‚ directional‚ specific‚ limited effects‚ part of nervous system c. paracrines: local tissue fluids‚ nondirectional‚ limited effects d. hormones: slower in onset‚ systemic in bloodstream‚ sustained effects 2.

different function. This includes the brain stem which connects to the spinal chord. The brains stem helps to perform basic functions for humans like heart rate‚ breathing‚ digesting food‚ and for sleeping. You can locate the brainstem below the limbic system. The Brainstem contains the pons and medulla. The pons is above the medulla and helps to perform motor control like sounds are transferred from the ear to the brain through the pons. It also helps with your consciousness and sleep. The pons is linked

Neuron‚ axon dendrite‚ synapse‚ neurotransmitter and receptor. Also include transient exuberance. Neuron consists of a cell body and branching fibers. Neurons can communicate by firing chemical or electrical signals. It is excitable and can transmit and process information through electrical and chemical signals. Those signals occur in synapses. Synapses are

Body Systems of Various Organisms All organisms in the world have a range of systems and organs in their body. Some organisms may share similar body systems while others have absolutely nothing in common. Several of those organisms include humans‚ pigs‚ crayfish‚ and earthworms. From their mushy‚ gushy organs to their soft‚ gentle skin‚ you may think‚ “How are humans and pigs possibly alike? Or a crayfish and an earthworm?” In many ways they may not be‚ but in other ways‚ they are very much alike

perception may be realistic but it may also be unrealistic. What matters is the individuals’ own evaluation of the situation‚ and this has an impact on the way that person confronts the stressful situation. The physiological changes of the sympathetic nervous system prepare the individual to either confront or escape from the source of stress “fight or flight” (Cannon 1914). The body’s stress response is arousal for example‚ increased blood pressure and providing glucose to the muscles. The adrenal
