SUB – TOPIC 1 – Structure, functions, care and grooming of the nose.

 

The nose is one of the sense organs. It is the organ of smell. It is also used for breathing.

               

                    The Structure of the Nose

 

As said earlier, the nose is the sense organ for smell. The top of the nose consists of bone while the rest is made of cartilage, small muscles and skin lined with a fine moist / wet mucous membrane. It is divided into two nostrils by a partition known as septum. The nerves of smell, which runs from the nose to the brain, are called olfactory nerves.

The nose also consists of tiny hairs at its entrance. These hairs act as filters for air entering into the lungs.

 

                   

Functions of the Nose

 

1. It is used for smelling
2. It acts as a passage 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.

 

Care of the Nose

We need to care for our Noses. Lack of care could cause Nasal infection; bleeding of the nose and breathing difficulties. To care for the nose therefore, we must:

1. Avoid poking the nostrils with fingers. Poking may cause wound and bleeding. 
2. Use handkerchiefs or tissue paper to blow our nose when we have cold.
3. Avoid pushing objects into the nose.
4. Blow the nose gently and avoid sniffing.
5. Avoid plucking the hair in the nose.
6. See a doctor in case of any nose infection or blockage of the nose through foreign object.

 

Activities/Evaluation

1. The nose is the sense organ for———–
2. State another use of the nose.
3. Mention 5 ways to care for your nose.

4.Draw a well-labeled diagram of the nose.

 

SUB-TOPIC II:  Structure, functions, care and grooming of the ear.                                 

 

The ear is the organ of hearing. It also helps us to maintain balance.

 

Structure of the Ear

 

The ear is made up of three parts;

The outer ear, middle ear, and the inner ear. The outer ear is like a funnel .It picks sounds and carries it to the eardrum .The eardrum is between the outer ear and the middle ear. The sound /vibration passes to the inner ear where it is transmitted through the auditory nerve to the brain for interpretation.

 

Functions of the Ear

1. It is the organ of hearing
2. It helps to maintain balance

 

CARE OF THE EAR

 

1. The ear like every organ is very delicate and should be well cared for by washing the outer ear daily and then wipe with clean towel.
2. Remove excess wax in the ear canal using cotton swab as gentle as possible.
3. Do not put any sharp object in the ear.
4. Report any form of ear ache to the doctor.
