Which of the following types of neurons is the least abundantly found in the nervous system? RATIONALE    Pseudo-Unipolar Neuron  Bipolar Neuron  Multipolar Neuron  Unipolar Neuron UNIT 4 — MILESTONE 4 22/25 CONCEPT  Nervous Tissue 2 Bipolar neurons have two processes, which extend from each end of the cell body, opposite to each other. One is the axon and one the dendrite. Bipolar cells are not very common. Bipolar neurons are the least common of the ...

AQA A-level BIOLOGY 7402/2 Paper 2 Mark scheme June 2022 Version: 1.0 Final. MARK SCHEME – A-LEVEL BIOLOGY – 7402/2 – JUNE 2022 2 Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation events which all associates participate in and is the scheme which was used by them in this examination. The standardisation process ensures that th...

the document focuses on the nervous system, from its functions to explaining sympathetic and parasympathetic nervous system. the document also contains general structure and functions of the neurone. the documents also contains sensory, relay, motor neurones information. It also explains the knee-jerk reflex and the glial cells. The documents also has stages of action potential and comparison between myelinated and non-myelinated. the saltatory conduction is explained using diagram and stages in...

what do sensory neurones do - Answer carry nervous impulses from receptors into the central nervous system (CNS) what do motor neurones do - Answer carry impulses from the CNS to the effector organs What do relay neurones do? - Answer relay neurones are intermediate neurones they recieve impulses from a sensory neurone and relay them to motor neurones what are dendrites - Answer carries nervous impulses towards a cell body what is an axon - Answer carry nervous impulses ...

What is homeostasis? - answer The maintenance of a constant internal environment. What is a stimulus? - answer A change in your environment than requires a response. e.g Light, sound, touch, pressure, pain, chemical or temperature. What do the receptors do? - answer Detect the stimulus or change in environment. What happens after the receptors? - answer Receptors send messages to the CNS via the sensory neurone. What makes up the central nervous system? - answer The brain or spinal cord ...

Abiotic components - Components of an ecosystem that are non living Abiotic factors - Non living components of an ecosystem that effect other living organisms Acetycholine - Chemical that acts as a transmitter that diffuses across synaptic cleft Acetycholinesterase - Enzyme in synaptic cleft that breaks down acetycholine. After it has triggered an action potential in the post synaptic neurone, acetycholine must be broken down otherwise it would remain in the synaptic cleft and continue to o...
