Somatic nervous system
Autonomic nervous system
Somatic nervous system
All the nerves controlling muscular system and external sensory receptors
Autonomic nervous system
Consists of the nerves that control internal organs
Sensory neurones
Carry messages from receptors to the CNS
Motor neurones
Transmit messages from the CNS to the effectors
Interneurones
Are found in the CNS and connect one type of Neurone to another
Sense organs
Allow for information to make its way to the nervous system and allow to the input of pain pressure and temperature
Receptors
Structures that recognise a stimulus
Effectors
Organs that carry out the body’s actions in response to motor neurone signals
Dendrites
Receive information from another nerve cell and transmit the message to the body
Plasma
Is the liquid portion of the blood it distributes substances it contains as it circulates throughout the body
Haemoglobin
A component of red blood cells that is responsible for carrying oxygen around the body
White blood cells
Part of our immune system and help fight infection
White blood cells (types)
Neutrophil Eosinophil Basophil Monocyte Lymphocyte
Platelets
Help blood clot and are formed in the bone marrow
Pathogens
Are microscopic organisms that can cause disease they include bacteria and viruses
Phagocytosis
The process by which white blood cells move from the blood to the tissues where the ingest and destroy foreign material
Lymphocytes
A type of white blood cell that when contacted by pathogens produce antibodies
Antibodies
Help destroy pathogens
The end of the antibody acts as a signal to the phagocytes to destroy the pathogen
Antigens
Are a protein or carbohydrate that is able to provoke the immune system of the host
