Musculo-Skeletal The adult There are about 600 muscles.in the human body human The three main types of skeleton is muscle include made up of ,Skeletal.206 bones Smooth Each upper.Cardiac limb is made of 30 bone- The brain, nerves and skeletal Adults muscles work together to Both upper cause movement – this is have limb arou =60 collectively known as the neuromuscular system nd 350- 360 joints Joints Boundaries –Contents of Cubital Fossa Contents From lateral to medial Radial nerve - originating from the posterior cord of the brachial plexus, with contributions from C5-T1 roots. In the cubital fossa, it runs close to the brachioradialis muscle and splits into its deep and superficial branches.within Biceps tendon biceps tendon runs through.attaching to the radial tuberosity of the radius Brachial artery - the brachial artery runs through the fossa, just medial to the biceps tendon, branching at the apex into the radial and.ulnar arteries Median nerve - originating from the lateral and medial cords of the brachial plexus, with contributions from C6-T1 roots. It can be found most medially within the cubital fossa, running between the two heads of pronator teres.in the majority of the population Anatomical Snuffbox Extensor pollicis Longus.1 2. Extensor pollicis Brevis 3. Abductor pollicis Longus 4. Radial artery crosses the floor of the anatomical snuffbox 5. Superficial branch of the radial nerve 6. Cephalic vein Base; Scaphoid, Styloid process of Radius ?How many bones are there in the upper limbs combined * 20.1 30.2 40.3 60.4 D ?Which bony landmark is located on the lateral side of the proximal humerus * greater tubercle.1.1 trochlea.2.2 lateral epicondyle.3.3 lesser tubercle.4.4 A.1 ?Which region of the humerus articulates with the radius as part of the elbow joint * trochlea.1 styloid process.2 capitulum.3 olecranon process.4 C ?Which is the lateral-most carpal bone of the proximal row * trapezium.1 hamate.2 pisiform.3 scaphoid.4 D.________ The radius bone * is found on the medial side of the forearm.1 has a head that articulates with the radial notch of the ulna.2 does not articulate with any of the carpal bones.3 has the radial tuberosity located near its distal end.4 B Left to right: Sagittal Coronal transverse : sagittal plane is an imaginary vertical plane passing through the center of the body dividing it into an equal right and left.halves Body Plane :Coronal plane is an imaginary vertical plane passing at a right angle to the median.sagittal plane Body Plane Horizontal (transverse) :plane is an imaginary horizontal plane passing at a right angle to the median sagittal.and coronal planes Anatomical Position – Terminology Medial: any structure situated nearer to the median plane of the body than another is said to be.medial to the other Lateral: any structure that lies farther away from the median plane of the body than another.is said to be lateral to the other Anatomical Position – Terminology :Anterior & posterior are used to indicate the front and back of the body respectively. Palmar & dorsal are used to describe the anterior & posterior surfaces of.the hand respectively Posterior Superior & inferior are used to indicate the levels, high or low with reference to the upper and lower ends of.the body :Proximal & distal are used to describe the relative distances from the root of the limbs, ex. arm is proximal to forearm & hand.is distal to forearm :Superficial and deep are used to indicate the relative distances of structures from the.surface of the body Superficial and deep Anatomical Position – Terminology Internal and external are used to describe the relative distances of structures from the.center of an organ or a cavity Ipsilateral refers to the same side of the.body Contralateral refers to the opposite side of the.body Anatomical Position – Terminology Supine position is that position in which the.individual lies on his back Prone position is the position in which the individual lies with face.downward Flexion- Extension Flexion is a movement that.takes place in sagittal plane Extension means straightening of the joint and usually takes place in a posterior direction, ex..extension of elbow joint Body Movements :Abd uction is the movement away from midline of the body in coronal.plane :Add uction is the movement toward the body.(midline) in the coronal plane Body Movements Pronation is a medial rotation of the forearm.so that palm faces posteriorly Supination is a lateral rotation of forearm from the pronated position so that the.palm faces anteriorly Rotation is the movement of part of the body.around its long axis Lateral flexion is a movement of the trunk in the.coronal plane Circumduction is a combination of flexion, extension, abduction and.adduction movements Protraction is a forward movement, ex. forward.movement of the jaw Retraction is a backward movement of a protruded.structure :Inversion is a movement of the foot so that the.sole faces medially :Eversion is a movement of the foot so that the.sole faces laterally Body Movements
