Verified step by step guidance

Understand the anatomical structure of vertebrae: Vertebrae are categorized into cervical, thoracic, lumbar, sacral, and coccygeal regions, each with distinct features and functions.

Focus on thoracic vertebrae: These vertebrae are located in the mid-back region and are characterized by their articulation with ribs, which gives them a unique shape.

Visualize the thoracic vertebrae: When viewed from behind, the spinous processes of thoracic vertebrae are long and point downward, resembling the head of a giraffe due to their distinct shape and arrangement.

Compare thoracic vertebrae to other types: Cervical vertebrae are smaller and have transverse foramina, lumbar vertebrae are larger and more robust, and sacral vertebrae are fused into the sacrum, none of which resemble a giraffe's head.

Conclude that thoracic vertebrae are the correct answer based on their unique anatomical features and resemblance to a giraffe's head when viewed posteriorly.
