Negative Feedback
Control system where a stimulus causes the system to diminish the effects of the stimulus
5 of 22
Positive Feedback
Control system where a stimulus causes the system to increase the stimulus

Two control systems in the body
Endocrine system and Nervous system
7 of 22
Division of Central nervous system
Somatic and Autonomic. Somatic controls skeletal muscle. Autonomic is sub divided to Parasympathetic and Sympathetic
8 of 22
Parasympathetic Nervous System
Long pre ganglionic nerve fibre. Short Post ganglionic nerve fibre. Acetyl choline. Rest and Digest. Cranial and Sacral..
9 of 22
Sympathetic Nervous System
Short pre ganglionic nerve fibre. Long post ganglionic nerve fibre. Fight or flight. Noradrenaline. Thoracic and Lumbar.

Four parts of blood vessel from outside to in.
Tunica adventitia, Tunica Media, Tunica intimia and Lumen
17 of 22
Tunica media structure
Contains smooth muscle fibres to allow constriction and dilation.
18 of 22
Tunica intima structure
Endothelia, Basement membrane and sub endothelia connective tissue
19 of 22
Tunica Adventitia
Merges with outside connective tissue, may contain blood vessels
20 of 22
3 types of Capillary
Continuos (Diffusion through cell wall) Fenestrated (Have pores allowing rapid water exchange) Sinusoidal (Large gaps allowing exchange of solutes))

3 types of Artery
Elastic, Muscular and Arterioles.
