Anatomical Language and Terminology It all seems Greek to me!!!! Often students complain that when they study anatomy it seems so hard because it’s like learning a foreign language. Well, it is! Most of the anatomical terms you will learn are Latin or Greek so it may take some time and effort to learn them Basic terms In the following pictures look for the following terms and their meanings: 1. Digits 6. Sternal 2. Abdominal 7. Thoracic 3. Oral 8. Axillary 4. Carpal 9. Coxal 5. Brachial 10. Hallux Some common anatomical terms Some more terms In the following pictures look for the following terms and their meanings; 1.Occipital 2. Gluteal 3. Popliteal 4. Plantar 5. Sacral 6. Lumbar 7. Cervical 8. Dorsal 9. Vertebral 10. Perineal Some more common anatomical terms Which is my front and which is my back??? There are many terms which refer to the alignment of one body part to another. These allow us to describe the location of muscles and other structures as well as allowing us to describe body orientation Basic terms Term Meaning Anterior The front of the body or towards the front The back of the body or towards the back The inner side or towards the middle of the body The outer side or towards the outside of the body Posterior Medial Lateral Some examples…. The chest is anterior to back. The buttocks are posterior to the stomach. The breastbone (sternum) is a medial structure. An ear is lateral to the nose. Superior Towards the head or the top of the body, or being on top Inferior Towards the feet or the bottom of the body, or being underneath Proximal Closer to the origin of the body part Distal Further away from the origin of the body part Superficial Towards the body’s surface Deep Away from the surface Some examples…. The head is superior to the neck. The navel is inferior to the chest The elbow is proximal to the wrist. The foot is distal to the knee. The skin is superficial to the bones. The lungs are deep to the ribs. Learning Tools On a friend point to: - the superior part of their arm; - their posterior trunk; - the distal part of the leg; - the superficial abdominal muscles. The body in space…… There are terms which describe body alignment and body position. Look at the following picture. We move in three dimensions As we swing our arms forward and backwards we move in the sagittal plane. As we take arms out to the side we move in the frontal plane. As we twist our hips in and out we move in the transverse plane. Movements mean Action ! Please refer to the video for demonstrations of different movements. Learning Tools Practise these movements with the video. Movements 1. Abduction / Adduction Abduction is taking the body part away from the middle of the body. Adduction is moving the body part towards the middle of the body. These movements occur in the frontal plane. Abduction and Adduction 2. Flexion/ Extension Flexion is when we bring the front surfaces together Extension is moving the body part backwards. The exception is with the knee ankle and toes, due to development in utero the opposite applies to the lower limb. These movements occur in the sagittal plane. Flexion and Extension Flexion and extension in the knee Flexion and extension in the ankle In the ankle, flexion is called plantarflexion and extension is called dorsiflexion 3. Circumduction Circumduction is when we move a joint around and around. The shoulder is able to be moved in such a way. 4. Medial / Internal Rotation – Lateral External Rotation Medial or internal rotation is when we twist a joint in towards the body Lateral or external rotation is when we twist a joint away from the body Medial and Lateral Rotation Medial rotation is when you take your hand towards to stomach, lateral rotation is when you take the hand away. 5. Inversion and Eversion Inversion and eversion are terms used to describe movement of the foot. Twisting the foot in is called inversion whilst twisting the foot out is called eversion Inversion and Eversion 6. Pronation and Supination Pronation and supination are the terms which describe the movement of the forearm. Supination is the movement which allows the palm of the hand to face upwards whilst pronation of the forearm allows the palm of the hand to face downwards. Pronation and Supination Learning tools Types of Contractions Muscles can contract in different ways:1. Concentric contractions 2. Eccentric contractions 3. Isometric contractions Concentric contractions A muscle contracts concentrically when it shortens its length and generates power. Some examples of a concentric contraction are a biceps curl, a hamstrings curl and doing triceps extensions. Eccentric contractions A muscle contracts eccentrically when it lengthens as it generates strength and power. Some examples of an eccentric contraction are squats (as you lower down) and negative reps” exercises in the gym where you lower weights slowly against gravity or lower your bodyweight down a stair. Some examples of concentric and eccentric contractions Isometric contractions A muscle contracts isometrically when it stays at the same length as it generates strength and power. Some examples of isometric contraction are when you are attempting to lift or move an immoveable object and when you hold a weight still at arm's length. An example of an isometric contractions
