Question

Breathing is controlled by ?

Answer 1

Hint: Centre for control of respiration Heartbeat and peristalsis is controlled by the brain medulla oblongata. Medulla oblongata controls the autonomic functions of the brain to the spinal cord for proper functioning of other body parts. It is also responsible for regulating basic functions of the nervous system.

Complete answer:
Medulla oblongata is a part of the brain that controls respiration, Heartbeat and peristalsis. It is a long stem-like structure that controls the autonomic functions and is also responsible for regulating functions of the nervous system.
Medulla oblongata is found at top of the spinal cord and contains a group of neurons that transmit electrical impulses to heart and lungs to control the action of respiration and breathing-rate, peristalsis and heart rate.
Further the medulla oblongata is divided into two parts: the superior part (upper open part )and inferior part that is lower closed part.
Brain has other different parts also that function differently for example the cerebral region is responsible for reasoning and emotions, Pons region deals with sleep cycle, respiration, eye movement, etc; they have centres for only sensory and motor control whereas cerebellum is associated with functions like balance, planning etc.

Note:
Medulla oblongata is the part of the brain that controls respiration, heartbeat and peristalsis. It controls the autonomic function of the part of the brain and connects the higher level of the brain to the spinal cord for the proper functioning of other organs.
Medulla oblongata is too responsible for regulation of basic functioning of the nervous system which includes respiration, and acts as Cardiac Centre and reflex Centre like coughing, sneezing etc.
