The Brain, the Spinal Cord and Reflexes

Name: The Brain, the Spinal Cord and Reflexes
Author: StemPy Lab

Which part of the brain keeps you breathing, and which part lets you read this line? You map the forebrain, the midbrain and the hindbrain, look at the spinal cord, and trace a reflex from the skin to the muscle and back. It serves the Indian syllabus (NCERT, NEET) and the matching topic of A-Level, IB and AP.

Lesson 1about 30 min
The coverings of the brain and the forebrain
The brain is the command and control centre of the body. The skull and three layers of cranial meninges protect it. The brain has a forebrain, a midbrain and a hindbrain. The forebrain holds the cerebrum with its two hemispheres, the thalamus, the hypothalamus and the limbic system.

Lesson 2about 25 min
The midbrain and the hindbrain
The midbrain lies between the forebrain and the hindbrain. A canal, the cerebral aqueduct, passes through it, and four swellings called the corpora quadrigemina lie on its back. The hindbrain has the pons, the cerebellum and the medulla. The medulla controls breathing and the reflexes of the heart, and it joins the spinal cord.

Lesson 3about 30 min
The spinal cord and the reflex arc
The spinal cord carries messages between the brain and the body, and it also runs reflexes. A reflex is a quick and involuntary response to a stimulus that does not need conscious effort. The reflex arc has at least one afferent neuron and one efferent neuron. In the knee jerk the impulse goes in through the dorsal root and out to the muscle.
