Question
The two loing bones in the forearm bones artkoulahe at sheir prosimal and distal ends to form the prosimal and Observe the uina and radius on ·skeleton which on·is the medial bone and which is the laceral bone Radal tuberosity Phoximal radkodnar Lateral bone anatomical position is useful for determining your answers Ulnar head Ulnar notch Distal Styloid process Stylold process of uina joint of radius Identify the following bone markings Radius 1. Radial head 2. Radial baberosity MAKING CONNECTIONS 3. Ulnar notch A long bone consists of a diaphysis (the shaft) and two epiphyses (the knoblike ends). Examine a humerus, a radius and an ulna. For each bone, list the bone markings that form the proximal epiphysis and the distal epiphysis. Bone Humerus 4. Styloid process of radius Ulna: 1. Olecranon 2. Trochlear noöch 3. Coronoid process Prasimal Epiphyis istal Epiphysis 4. Radial notch 5. Ulnar head 6. Styloid process of ulna Both the radius and ulna articulate with the humerus at the elbow joint.Identify the bone markings that articulate between the humerus and radius, and between the humerus and ulna at the elbow joint. Radius Artdiculacing Bones Bone Markings Humerus and Humerus radius Ulna Humerus and Humerus UlnaExplanation / Answer
3)
i) Humerus and radius- bone marking: humerus- capitulum
Radius: head
ii) humerus and ulna- humerus - trochlea
Ulna- trochlear notch.
making connections:
1) humerus -
proximal epiphysis (near the torso) - head of the humerus. It starts with surgical neck. Consist of greater tubercle, lesser tubercle and anatomical neck.
Distal epiphysis consists of - it starts with supercondylar ridge (medial and lateral).it consists of radial fossa, medial epicondyle, lateral epicondyle, capitulum, trochlea
2) Radius
- proximal epiphysis- head, radial notch , tuberosity
Distal epiphysis- consist of radial column, lunate fossa, scaphoid fossa, and styloid process of radius.
3) Ulna
proximal epiphysis: trochlear notch, radial notch, olecranon process
Distal epiphysis: ulnar column and ulnocarpal disk
