🔴 ANATOMIA 👉 SEGMENTOS CORPORALES 🟩 ANATOMÍA GENERALIDADES #2 🟪 Hablemos de Anatomía y Algo Mas...🟥

New Section

In this section, the speaker introduces the basic body segments, including the head, neck, trunk, upper limbs, and lower limbs. The distinction between colloquial terms like "arm" and anatomical terms like "upper limb" is highlighted.

Basic Body Segments

• The upper body segment is anatomically referred to as the "upper limb," consisting of the right and left arms with distinct segments.

• Exploring each segment of the head initiates with understanding that it is the superior segment of the human body. The delineation between the head and neck is marked by specific anatomical points.

• Common misconceptions in anatomy include equating the head with just the skull; however, anatomically, it comprises both skull (cranium) and face.

• Anatomically, the head is divided into cranium and face with a clear boundary defined by specific points such as frontal bones and nasal bones.

• Emphasizing that while English terminology may refer to "skull" as part of the head, in anatomy, it constitutes only a portion alongside the face.

New Section

This section delves deeper into distinguishing between facial structures like "face" and "facial massif," elucidating their differences based on mobility and components.

Facial Structures Differentiation

• Clarification on terminology: "face" encompasses all facial bones while "facial massif" excludes mandible due to its mobility at temporomandibular joint (TMJ).

• Highlighting that facial massif refers to immobile facial structures except for mandible due to its articulation at TMJ.

New Section

Transitioning from discussing facial structures to exploring neck anatomy including boundaries and key landmarks defining its limits.

Neck Anatomy Exploration

• The transition from head to neck occurs logically where neck begins where head ends. Understanding boundaries helps differentiate between neck and trunk regions.

• Illustrating how sternum's superior border to C7-T1 intervertebral disc marks clear demarcation between neck (above) and trunk (below).

New Section

In this section, the speaker discusses the division of the trunk into three segments and defines the boundaries of each segment.

Trunk Division and Boundaries

• The trunk is divided into three segments: the lower limit of the neck serves as the upper limit, while the perineum acts as the lower limit.

• The perineum comprises soft tissues that close below the inferior opening of the pelvis, providing a floor to the pelvis.

• The pelvis resembles a vase without a base, with its base formed by a combination of soft components known as perineum.

New Section

This part focuses on discussing how the trunk serves as an anchor for both upper and lower extremities, further dividing it into three distinct segments.

Trunk Segmentation

• The trunk serves as an anchor for both upper and lower extremities.

• The trunk is divided into three segments: thorax, abdomen, and pelvis.

• Each segment of the trunk has clear boundaries; for instance, between thorax and abdomen lies the diaphragm which separates them distinctly.

New Section

This section delves into understanding and defining the upper limb's structure in anatomical terms.

Upper Limb Anatomy

• The upper limb consists of six segments: shoulder, arm, elbow, forearm, wrist, and hand.

• Anatomically speaking, when referring to "arm," it specifically denotes this segment within the upper limb structure.

• Understanding anatomical terminology aids in precise communication regarding body parts; distinguishing between arm and other segments becomes crucial in medical contexts.
