Answer #1

AUTONOMIC NERVOUS SYSTEM SIMILARITY

SYMPATHETIC & PARASYMPATHETIC

PREGANGIONIC FIBRE CHOLINERGIC

MAINTAIN HOMEOSTASIS

DIFFERENCE

SYMPATHETIC PARASYMPATHETIC

POSTGANGIONIC FIBRE ARE NOREPINEPHRINE

GANGLION NEAR THE SPINAL GLAND

ACTIVE DURING FLIGHT FRIGHT , EMERGENCY SITUATION

INCREASE HEART RATE ,DILATE PUPIL

Length of fibre

Pregangionic - short

Postgangionic -long

POST GANGLIONIC ARE CHOLINERGIC

GANGLION AWAY FROM SPINAL CORD AND NEAR THE ORGAN

ACTIVE DURING RELAXATION

DECREASE HEART RATE, CONTRICT PUPIL

Length of fibre

Pregangionic- long

Postgangionic-short
