In SC116 Unit 4 the captions carry the marks, and this finished system diagram analysis labels a long bone section precisely before arguing function from structure. Searches like "sc 116 unit 4 assignment example", "sc116 unit 4 sample" and "sc116 unit 4 example" land here.
What a finished SC116 Unit 4 system diagram analysis looks like
The figure comes first, a longitudinal section of a femur with leader lines that end exactly on the structure named: diaphysis, proximal and distal epiphyses, epiphyseal line, articular cartilage, periosteum, endosteum, compact bone, spongy bone, medullary cavity, and red and yellow marrow. Beneath it sit numbered captions, one per group of labels, each two to four sentences long. The caption for the diaphysis argues that a tube of compact bone resists bending with less mass than a solid rod would. The caption for the epiphyses explains that the lattice of spongy bone distributes forces arriving from many directions at the joint and houses red marrow. The articular cartilage caption links its smooth, avascular surface to low-friction movement. Its last paragraph turns to the muscular system, noting where tendons attach and why the rough surface there matters.
How a SC116 Unit 4 example is structured
A brief introduction names the figure, its source if supplied, and its orientation, including which end is proximal. The labeled figure follows, then the captions in the order a reader's eye would travel, usually from the shaft outward to the ends. Each caption follows a consistent internal pattern: the structure named, its composition described, and its function argued from that composition. After the captions, a short analysis section addresses one question the figure raises, often why the epiphyseal line appears in an adult bone and what it records about growth. A final paragraph ties the skeletal figure to movement by naming a muscle that attaches near the figure's proximal end and the action it produces. Where a section supplies a muscular figure instead, the same order applies: labels first, captions arguing from fiber arrangement to force.
Leader lines that land
Each line ends on the structure it names, the periosteum on the outer membrane rather than on compact bone beneath it, because a misplaced tip reads as a wrong answer.
Captions that argue
Every caption moves from what a structure is made of to why that composition suits its job. A caption that only restates the label earns nothing the label had not already earned.
Orientation stated
The introduction says which end of the femur is proximal and which surface is anterior, so every label and caption can be checked against a fixed frame.
The epiphyseal line explained
One analytic paragraph explains what the line records, the former growth plate, which shows the figure was read as evidence of a process rather than as a static picture.
A bridge to muscle
The final paragraph names a muscle attaching near the proximal end and the movement it produces, linking the skeletal figure to the system that moves it.
Where marks go in SC116 Unit 4
Restating the label is the caption failure graders meet most often, a caption reading this is the diaphysis earning none of the reasoning share that SC116 figures typically carry. Leader lines that end near the right structure rather than on it follow closely, and most graders mark them as incorrect. Confusing the epiphyseal line with the epiphyseal plate, or placing red marrow in the adult medullary cavity of the shaft, costs accuracy points in many sections. A figure with no stated orientation leaves proximal and distal labels impossible to check. Some rubrics deduct for captions longer than the space allows or for a figure reproduced without its source. Missing the connection to movement, and terminology that shifts between labels and captions, account for the smaller losses.

SC116 Unit 4 questions, answered
Can I draw the figure myself?
Many sections allow or even require it, and a hand drawing is often fine as long as it is clear and the labels are placed precisely. Proportion matters less than accuracy of placement. If you draw it, state your source for reference, such as the course text figure you worked from, and make sure every leader line ends on the structure it names.
How long should each caption be?
Usually two to four sentences, unless the prompt sets a limit. That is enough to name the structure, describe its composition and argue its function. Captions that run to a paragraph each can crowd the page and bury the figure. If space is tight, group related labels under a single caption rather than shortening each one to a fragment.
What if my section assigns a muscle figure instead?
The same approach applies. Label origins, insertions and bellies precisely, then write captions that argue from structure to action, such as how a muscle's line of pull across a joint determines the movement it produces. Naming the antagonist in the caption is a simple way to show that you understand how the muscle works within the system.
