T Level Health - The Nervous System

5 Powerpoints covering The Nervous System for T Level Health, Core B further science concepts. Includes a Powerpoint on exam technique for 12 mark questions. Templates adapted from Canva. All content is adapted from my own knowledge, Google images, and T Level Health textbook.

B2.17 The role of the components in performing the functions of the nervous system:
• components of the nervous system:
o brain
o spinal cord
o sensory and motor neurones:
▪ dendrites, cell body, nucleus, axon, myelin sheath of Schwann cells, nodes of Ranvier, axon
endings/terminals and synaptic ends
o relay neurones
o synapses
• function of the relevant component of the nervous system:
o sensory neurones carry impulses from receptors to the central nervous system (CNS)
o motor neurones carry impulses away from the CNS to effectors
o the process of synaptic transmission and the function of the components of a motor neurone
B2.18 The mechanism of nerve impulses via neurones:
• transmission of action potentials along neurones
• mechanism of a reflex action
B2.19 The development, impact and management of Parkinson’s disease:
• causes of the disease
• impact on systems within the body and on physical and mental health
• how common treatments relieve symptoms:
o supportive therapies
o levodopa medication
o surgery, to include deep brain stimulation
