Resting
- The neuron is at rest at about –70mV

- Sodium (Na⁺) is mostly outside the cell and potassium (K⁺) is mostly inside

- The cell is ready to respond if it gets a signal

Depolarisation
- When a stimulus is strong enough, sodium channels open and Na⁺ rushes in

- Making the inside of the neuron more positive which moves the voltage up towards +30mV

Repolarisation
- Sodium channels close and potassium channels open

- K⁺ moves out of the cell, making the inside negative again and bringing the voltage back down

Hyperpolarisation
- Potassium channels stay open a bit too long, so the inside becomes more negative than resting

- The sodium-potassium pump restores the balance

- Neuron returns to resting state

• cardiac cycle: sequence of events in one heart beat (contraction (systole) and relaxation (diastole) of the atria and ventricles).

• pulmonary circuit: Pathway of blood flow from the heart to the lungs and back. Deoxygenated blood is pumped from the right ventricle to the lungs to recieve oxygen and release carbon dioxide before returning to the left atrium.

• cardiac output: total volume of blood pumped by one ventricle per minute. (Cardiac Output = Heart Rate x Stroke volume)

• stroke volume: amount of blood pumped out of one ventricle with each heartbeat.

• diastole: Phase of the cardiac cycle when the heart muscles relax, allowing the chambers to fill with blood.

• systemic circuit: Circulation of ocygenated blood from the left ventricle to the rest of the body and the return of deoxygenated blood to the right atrium.

• heart rate: Amount of beats per minute of blood pumping through the body.

• systole: phase of the heart contractracting to pump the blood out to the lungs and the rest of the body.

During filtration the solutes that can pass through the filtration membrane of the glomerulus are small molecules of H2O, Na+, K+, CI-, Ca2+, HCO-3, PO34-, glucose, amino acids, fatty acids, urea, and other small waste products.

Larger molecules (like proteins and blood cells) cannot be filtered out, as they are normally retained in the blood stream.

1. How do you feel about the mark and feedback recieved? Did it match your expectations?

The marking l got from my first quiz actually had me in shock as l was not expecting to recieve a grading level of Distinction. I thought l would have recieved a grade C or P1 considering l had been struggling with some cases of understanding the content, but from my results it shows that l studied well.

2. What strategies did you use to prepare for the quiz?

To ensure that l was prepared for the quiz, I ensured that l revised all information, and the best strategy that had worked for me was repetition. Repeating the questions provided (short quiz) allows my mind to understand the concepts of questions that l will recieve, and how l can use the content l learnt into situations/ questions l may be asked in the future.

3. What strategies will you use when preparing for the next quiz? This could include any changes to your revision or test preparations that you might trial if you identified some challenges in the first quiz.

The strategies l will use for the next quiz are the same, repetition, and revising content as it worked really well considering my results from the first quiz.

The poster that is based on "The Respiratory System: Every breath you take" significantly presents itself as an HD. The reason why this poster was given an HD.

The "Physiology Poster Muscles" poster was presented as a F1 (Fail 1) after marking. The poster layout was very limited and messy, not consisting in clear layout and explainations of phyisiolgy concepts/ support.

While "The Respiratory System: Every Breath You Take" clearly was presented as a HD (High Distinction). Example, it shows clear understanding through the content they have deeply researched, providing their figures with brief explanations compared to the "Physiology Poster Muscles". The content provided on the poster was explained effictevly, and covered all topics explaining the respitory system.

In this stage of the Sliding Filament Theory, the energised myosin heads bind to exposed binding sites on the actin filaments, forming a temporary link called a cross bridge.

Dr. Matt and Dr. Mike's youtube channel has provided almost every topic for this course that we have covered. It was recommended by a friend in previous nursing that they had used this to help them understand, and it really does help! I usually try and find a video of theirs after learning the course content first, to make sure that l understand it.
