- The Nervous System & Neurons
- Neurons
- Motor Neurons
- Carry messages away from the brain and spinal cord to the organs and muscles in the body
- Short dendrites and long axons
- Sensory Neurons
- Carry messages from the receptors in the body to the brain and spinal cord.
- Long dendrites and short axons
- Interconnecting Neurons
- Only found in our visual system, brain and spinal cord.
- Recieve messages from the sensory neurons and pass them to either to interconnecting neurons or motor neurons
- Short dendrites and short or long axons
- Synaptic Transmission
- A synapse is a specialised gap that allows electrical messages from one neuron to transfer to an adjacent neuron. known as synaptic transmission
- Dopamine, Acetylcholine, Serotonin are Neurotransmitters
- Motor Neurons
- The Nervous System
- Peripheral Nervous System
- Autonomic Nervous System
- Sympathetic Nervous System
- Fight or Flight Response
- Dilates pupils, inhibits saliva production, Dilates Bronchi, Speeds up heart rate etc..
- Parasympathetic Nervous System
- Rest & Digest
- Constricts Pupils, Stimulates saliva production, Constricts Bronchi, slows heart rate etc...
- Maintains homeostasis by controlling glands and vital muscles.
- Sympathetic Nervous System
- Somatic Nervous System
- Controls skeletal muscles and receives information to a from sensory receptors
- Autonomic Nervous System
- Central Nervous System
- Brain
- Spinal Cord
- Peripheral Nervous System
- The Endocrine System
- Composed of a number of glands that release hormones directly into the bloodstream.
- One of the main glands is the pituitary gland, which releases ACTH which is carried around the body to stimulate the adrenal glands to release adrenaline
- Neurons
