📚 Human Skeleton Labelling Mark Scheme | 人体骨骼标签评分方案

In KS3 CIE Biology, labelling the human skeleton is a common assessment task. A mark scheme shows you exactly where marks are given for correct bone names and arrow placement. This guide explains the key labels, common errors, and how to earn full marks.

在 KS3 CIE 生物课程中，标注人体骨骼是常见的考查任务。评分方案会明确告诉你哪些位置给分，包括正确骨骼名称和箭头指向。本指南解释关键标签、常见错误以及如何获得满分。

1. How to Use a Mark Scheme | 如何使用评分方案

A mark scheme tells the examiner where to award marks. For labelling tasks, one mark is usually given for each correct label placed accurately on the diagram. You should write the bone name at the end of the pointer line, not elsewhere.

评分方案告诉考官在哪里给分。对于标注题，通常每个正确标注在图上准确位置得 1 分。你应该把骨骼名称写在指示线末端，而不是其他位置。

CIE mark schemes often use short commands such as ‘accept’ and ‘reject’. ‘Accept’ means an alternative answer is allowed; ‘reject’ means the answer is wrong and no mark is given.

CIE 评分方案常用简短指令，如 ‘accept’（接受）和 ‘reject’（拒绝）。’Accept’ 表示允许替代答案；’reject’ 表示答案错误，不给分。

Always read the question carefully. If it asks for the scientific name, do not write only a common name unless the mark scheme says it is accepted.

务必仔细读题。如果题目要求科学名称，就不要只写常用名称，除非评分方案说明可以接受。

2. The Axial Skeleton: Skull and Face | 中轴骨骼：颅骨和面部

The axial skeleton is the central part of the skeleton. It includes the skull, vertebral column, ribs and sternum. Its main job is to protect the brain, spinal cord and organs in the chest.

中轴骨骼是骨骼的中央部分。它包括颅骨、脊柱、肋骨和胸骨。它的主要功能是保护大脑、脊髓和胸腔器官。

The skull can be divided into the cranium and facial bones. The cranium is the rounded part that covers the brain. The facial bones include the mandible and maxilla.

颅骨可分为脑颅和面颅骨。脑颅是覆盖大脑的圆形部分。面颅骨包括下颌骨和上颌骨。

When labelling the skull, an arrow pointing to the top or back of the head usually means ‘cranium’. An arrow pointing to the lower jaw
