CNS |
Brain and spinal cord |
|
Cerebellum |
Controls your balance and posture |
|
Cerebrum |
Controls your thinking, memory, speaking and movement-identifies information identified by your sense organs |
|
Medulla/Brain stem |
controls your heartbeat, breathing and blood pressure |
|
Pituitary Gland |
Regulates the functions of other endocrine glands. Produces hormones, pituitary growth, anti-diuretic, thyroid-stimulating |
|
Hypothalamus |
Responsible for hormone production. Produces a wide range of neurohormones |
|
Spinal cord |
Send messages to the brain, and from brain to PNS |
|
PNS |
Nerves, somatic and autonomic nervous systems. Sympathetic and parasympathetic nervous systems |
|
Neurotransmitter |
Chemical located at synaptic terminal that converts electrical impulse 'info', so that it can diffuse across the synapse to the next neuron. |
|
Motor neurons |
Take messages from CNS to effectors |
|
Sensory neurons |
convert external stimuli and transmit those messages to CNS |
|
relay neurons |
In CNS only, connect motor and sensory together |
|
Axon |
transmits info from dendrites to axon terminal |
|
Myelin sheath |
For protection and insulation of axon. Keeps electrical signals inside axon and helps them move faster. |
|
Dendrites |
Pass info from other neutrons into itself for transmission to another neuron |
|
cell body |
production of proteins |
|
Thyroid-stimulating |
changes rate of thyroxine. Produced by pituitary gland |
|
Anti-diuretic |
reduces amount of water reabsorbed by kidneys. Produced by pituitary gland |
|
Pituitary growth |
Stimulates muscle growth and controls bone size. Produced by pituitary gland. |
|
Thyroid |
Produces Thyroxine and Cacitonin |
|
Thyroxine |
Metabolism, physical and mental development. Produced by the thyroid gland. |
|
Cacitonin |
decreases amount of calcium in the blood. Produced by thyroid gland |
|
Thymus gland |
Produces Thymosin |
|
Thymosin |
disease fighting T-lymphocytes |
|
Adrenal gland |
Produces adrenalin. |
|
Adrenalin |
Fight or flight response |
|
Ovaries |
produces Progesterone and Oestrogen |
|
Progesterone |
controls thickness of uterus |
|
Oestrogen |
development f sexual characteristics, aspects of pregnancy and foetal development |
|
Testes |
Produces Oestrogen, Testosterone and Progesterone |
|
Oestrogen, Testosterone and Progesterone |
Sexual development and characteristics, sperm production |
|
Pancreas |
Produces Insulin and glucagon |
|
Insulin |
lowers blood glucose level |
|
Glucagon |
raises blood glucose level |
