Muscle fibres - Study guides, Revision notes & Summaries

a collection of lymphoid tissue found at the back of the tonsils is called: - adenoids or tonsills a dome shaped muscle that relaxes and contracts. - the diaphragm. Aeorbic Respiration - taking in enough oxygen to supply fuel for our muscles to complete everyday tasks) anaerobic respiration - Respiration that does not require oxygen ( exersize ) appearance of cancellous bone: - sponge honeycomb appearance. makes bones lighter filled with red bone marrow end of long, irregular, flat and ...

_____ bring a cell to threshold while _____ bring a cell further from threshold - ️️EPSPs; IPSPs Describe the mechanism of fusimotor drive - ️️muscle spindles are parallel to extrafusal fibres; the extrafusal fibres shorten when they contract, and the gamamotorneuron causes the intrafusal fibres to contract in order to maintain tension in the centre of the muscle spindle so it is still able to detect muscle stretch thoughout the entire ROM What things determine the type of cell tha...

IB Biology SL — Topic 1 • Cell Biology with Complete Solutions Cell theory 1. All living things are composed of cells 2. Cells are the smallest unit of life 3. Cells only arise from pre-existing cells Striated muscle cell Exception to cell theory! → Muscle cells fuse to form fibres that may be very long (>300mm) → Consequently, they have multiple nuclei despite being surrounded by a single, continuous plasma membrane → Challenges the idea that cells always funct...

Does ventilation increase with exercise? - ️️Fitness doesn't increase ventilation Type 1 Muscle Fibres - ️️Slow contraction time, small motor neuron, highly resistant to fatigue, low force production but high mitochondria and capillary density. Type 1 fibres are constantly working underneath and used for aerobic activity. Type 11a Fibres - ️️Moderately fast contraction time, medium motor neuron, medium force production and used for long term anaerobic activity <30min Typ...
