Unit description Unit description

This Unit considers the structure and function of the nervous system. We begin with an overview of the functional organization of the central and peripheral divisions of the nervous system. We discuss how the selective permeability of the cell membrane gives rise to the electrical properties of excitable cells. We look in detail at the generation, propagation and transmission of neural signals, and examine the important principles of sensory physiology such as transduction, adaptation and stimulus coding. Having covered these basic principles, the unit goes on to explore the somatosensory system, and the nerves and organs that give rise to the special senses (vision, hearing, taste and smell) are also discussed. We next examine the structure and physiology of muscle cells, and the central control of motor function. Lastly, we cover the autonomic nervous system and the neuroendocrine system, both of which regulate numerous physiological processes throughout the body.

General Assessment Information

Requirements to pass this unit

To pass this unit, you must achieve a total mark equal to, or greater than, 50%.

Late Assessment Submission Penalty

Unless a Special Consideration request has been submitted and approved, a 5% penalty (of the total possible mark of the task will be applied each day a written report or presentation assessment is not submitted, up until the 7th day (including weekends). After the 7th day, a grade of ‘0’ will be awarded even if the assessment is submitted. The submission time for all uploaded assessments is 11:55 pm. A 1-hour grace period will be provided to students who experience a technical concern.

For example, an assessment worth 20% is due 11.55 pm on 1 January. Student A submits the assessment at 10 pm, 3 January. The assessment received a mark of 18/20. A 10% deduction is then applied to the total possible mark (20), resulting in the loss of two (2) marks. Student A is then awarded a final mark of 16/20.

For any late submissions of time-sensitive tasks, such as scheduled tests/exams, performance assessments/presentations, and/or scheduled practical assessments/labs, please apply for Special Consideration. 

Assessments where Late Submissions will be accepted:

Lab reports and scientific poster - YES, Standard Late Penalty applies

Online quizzes - NO, unless special consideration is granted

Special Consideration

The Special Consideration Policy aims to support students who have been impacted by short-term circumstances or events that are serious, unavoidable and significantly disruptive, and which may affect their performance in assessment. If you experience circumstances or events that affect your ability to complete the assessments in this unit on time, please inform the convenor and submit a Special Consideration request through ask.mq.edu.au.

Online quizzes

The five quizzes are 30-minute online quizzes that you may do at home. Each quiz will be open for 7 days and consist of 12 questions. Quiz questions can be multiple-choice, short answers, fill in the blanks or calculations. Only one attempt at each quiz is allowed. You will see only one question at a time but you can go back to review your answers at any point. Think carefully before answering and budget your overall time carefully. You will be expected to use correct spelling and grammar in your answers.

Lab reports and scientific poster

The two lab reports and one scientific poster are based on data you will obtain during the practical classes. If you miss the practical classes, or for whatever reason do not have this data, please contact the unit convenor. A marking rubric is provided for each assessment. Please pay close attention to this marking rubric, as this is what the markers will base your grade on.

Final exam

The exam is a two-hour paper with multiple choice questions and short answer questions. All the lecture and practical material is examinable.

Delivery and Resources

Recommended text

The textbook for this unit is “Principles of Human Physiology” by Cindy L Stanfield, published by Pearson. Available electronically through the 'Unit readings - Leganto' Block in iLearn.

Week 1

Lectures will commence in week 1. Practical classes will be offered in intensive-mode, beginning in the mid-session break. Please refer to your personal timetable and the sections below for more information.

Lectures 

There will be two lectures each week. No in-person lectures for this unit. Each week's lectures will be made available through H5P. Lectures are often broken up into shorter chunks to make them easier to listen to, and are linked very closely to the textbook material so the supporting reading is very clear. All lecture notes will be available in the week-by-week sections on iLearn.
