14.1 Nervous Control in humans & 14.2 Sense Organs

14.1 Nervous Control notes and 14.2 Sense Organs notes in downloadable word format.

A lesson on Nervous System and Reflex Arc from Mr Dare:

A lesson on the Eye and Pupil Reflex from Mr Dare:

And finally, a lesson on Accommodation from Mr Dare:

Science Bank 15 (Responding to Stimuli): Part 1 – the Eye (to 5m 30s); Part 2 – the Nervous System (to 9m 25s):

GCSE Bitesize revises The Nervous System (in 8m 27s) and here’s a short (less than 5 minute) video clip from BBC iScience – The Eye.

Other videos include Science in Focus – Wired Nervous System (22m 51s), The Virtual Body – Sensory Systems (19m) & BBC Short Circuit The Eye (19m).

11.2 Movement

11.2 Movement from Bob Smullen

Here is another presentation, taking you through muscle contraction step by step:

Two video lessons on 11.2 Movement: a 7m video from Luiz Mello and a 15m video from Briscucation.

A 5m TED-Ed intro to How the Muscular System works and from Crash Course, Muscles, part 1 – Muscle Cells: Crash Course A&P #21 in 10m and Muscles, part 2 – Organismal Level: Crash Course A&P #22 in 10m 40s.

Paul Andersen explains The Muscular System in 5m 59s.

In Crash Course Biology #30 The Skeletal System: It’s ALIVE!, Hank introduces us to the framework of our bodies, our skeleton and in #31 – Big Guns: The Muscular System, he tells us the story of the complicated chemical dance that allows our skeletal muscles to contract and relax.

6.5 Neurons & Synapses

BioKnowledgy Presentation on 6.5 Neurons and synapses from Chris Paine

6.5 Neurons & Synapses notes to complete (created by Mrs Green).

IB Bio Topic 6.5 Pt A Neurons a 4m video lesson and IB Bio Topic 6.5 Pt B Neurons another 4m video lesson, from roxprice.

How do Nerves Carry Information? a 6m40s lesson from Naked Science Scrapbook.

In Crash Course Biology #26 – The Nervous System, Hank begins a series of videos on organ systems with a look at the nervous system and all of the things that it is responsible for in the body.

Fantastic animated tutorials from McGraw Hill Education – the Nerve Impulse, Action Potential propagation in unmyelinated axons, Voltage-gated channels &  the action potential, Sodium-Potassium exchange pump,  how it works & transmission across a synapse

From Sinauer Associates we have an animated, narrated tutorial on Reflex Arcs which also includes a quiz and here are animated, narrated tutorials on the synapse and action potentials.
