SUB-TOPIC: THE HAIR AND THE EYES

Each hair grows from a narrow tube in the skin called hair  follicle. Each follicle has a tiny oil gland near its base. The gland produces oil that lubricates the hair and softens the skin around it.

 

FUNCTIONS OF THE HAIR

1. it protects the head
2. it keeps the head warm in cold weather
3. it improves personal appearance and adds beauty to a person 

 

WAYS OF CARING FOR THE HAIR

2. Combing or brushing the hair thoroughly to remove dirt and dry scales (dandruff). It also stimulates the circulation of blood and keep the hair healthy.
3. Oiling the hair regularly to prevent dryness of the hair and scalp. Excessive dryness could lead to hair damage.

 

TOPIC: STRUCTURE OF THE EYE

the eye is one of the five sense organs . It is for seeing.  The eye is made up of different parts. Each part performs a special function. An understanding of the different parts of the eye will help you take good care of your eyes 

 

PARTS AND FUNCTIONS OF THE EYES

The eyebrow	Prevents sweat from running down into the eyes
The eye lashes	Protects the eyes from dust and dirt
The eye lids	Can close to protect the eye from foreign object
The eye balls	These are the organs of sight. Each is connected to the brain by the sensory nerve called optical nerve
Cornea	A protective layer. It keeps dust and dirt from passing through the pupil of the eyes.
The iris	The coloured part of the eye. It surrounds the pupil.
The pupil	The hole in front of the eyeball through which light rays pass into the eye
The lens	A glass-like part of the eye, it focuses the light rays into one spot on the retina thus forming the image.
The retina	A light sensitive spot  where images are formed
Tear gland	Pours out tear over the front of the eyes. The tear washes away any dust which enters the eye.

WEEK: FOUR

TOPIC: THE HUMAN BODY 

SUB-TOPIC: THE NOSE AND EAR 

 

The nose is the organ of smell. The very top of the nose consists of bone. The rest is made of cartilage, small muscles and skin lined with a fine moist mucous membrane. The lining of the membrane contains small glands which produce watery secretion. The secretion keeps the lining moist.  The nose is divided into two nostrils by a partition called septum. The nerves of smell which run from the nose to the brain are called olfactory nerves there are tiny hairs at the entrance of the nose. They act as filters for the air that goes to the lungs. 

 

FUNCTIONS OF THE NOSE

1. It is the sense organ of smell
2. It acts as a passage or channel through which the air we breathe passes in and out of the lungs
3. The air entering the lungs is filtered and warmed by the tiny hairs at the entrance of the nostrils.

[mediator_tech]

THE EAR (Structure)

The ear is divided into three parts; the outer ear, the middle ear and inner ear. The outer ear is the part we see. It looks like a funnel. It picks sounds or vibrations. The vibrations are carried to the eardrum, which is between the outer ear and the middle ear. The sound then passes through the auditory nerve.  There are tiny hairs at the entrance of the outer ear. These trap dust and any tiny insects or objects that try to enter the inner parts of the ear. The passage also contains wax which further helps to trap the dust and other objects.

 

Functions of the ear

1. It is the sense organ for hearing
2. It helps us to maintain balance.
