Executive Summary

Overview of body systems, reference points, and scientific vocabulary commonly used in advanced anatomical discussions of handballing and the fist chute.

Reference Points

Anatomists and medical professionals use specific directional terms and reference points to ensure consistency in understanding. The fisting population and the Fist Theory courses typically avoid these terms whenever possible; however, two directional terms and two positional terms are occasionally used for brevity or clarity.

The terms supine and prone refer to the two most common fisting positions for bottoms: face up (on his back) or face down (on his knees).

VOCABULARY

Supine

  1. Adjective (of a person) lying face upward or on his back.

Prone

  1. Adjective (of a person) lying face downward or on his stomach; in fisting, typically face downward on knees.
Bottom in Prone Position
Figure 1-1: Prone Position

Fisting on the knees is an example of the prone fisting position. Bottom: @sandiegofist.[ 1 ]

Bottom in Supine Position
Figure 1-2: Supine Position
©

Fisting in a sling or lying on one's back are examples of the supine position. Bottom: @sandiegofist.[ 2 ]

The directional terms medial and lateral indicate the general location of a hand inside the deeper regions of fist chute.

Hand in Lateral Direction
Figure 1-3: Lateral Direction

Directing the hand away from the center of the body toward the bottom’s side demonstrates the lateral direction.

Hand in Medial Direction
Figure 1-4: Medial Direction

Directing the hand toward the center of the body instead of the side demonstrates the medial direction.

VOCABULARY

Lateral

  1. Adjective situated on one side or other of the body or of an organ, especially in the region furthest from the center of the body.

Medial

  1. Adjective situated near the center of the body or the midline of an organ.

Body Systems

Anatomical courses discuss components of the fist chute according to their composite body systems and relevant neighboring organs:

System Components
Digestive Organs of the GI tract (responsible for absorption and excretion) including the dual-purpose sexual organs: anal canal, rectum, and colon.
Muscle Muscles and tendons responsible for movement and body maintenance, specifically muscles of the arms, wrists, hands and the muscles surrounding the fist chute.
Skeletal Bones and ligaments responsible for structure and alignment that facilitate manual penetration.
Integumentary Skin that is exposed externally to the environment and internally along the GI and respiratory tracts. Also includes tissues relevant to the fist chute.
Reproductive Organs related to sexual function and pleasure encountered during fisting, specifically the prostate.
Nervous Voluntary (somatic) and involuntary (autonomic) nervous systems that affect the ability to give and take a hand.
Table 2-1: Major Body Systems of the Fist Chute

Organs and tissues of several body systems are stimulated or manipulated during fisting and if managed correctly, can provide immense pleasure. If managed incorrectly, they will be a source of discomfort.

 

In addition to the major systems, some Fist Theory courses reference or address the other body systems:

System Components
Urinary Organs of the urinary tract and associated physiological functions, including those encountered and affected while fisting (urethra, bladder, and kidneys).
Respiratory Organs of the respiratory tract and associated physiological functions, including vocal cords, lungs, and nasal and oral cavities.
Cardiovascular The circulatory system and associated physiological functions, including vascular responses to inhalants and anal penetration.
Endocrine Glands and hormones that affect disposition and physiological functions.
Immune Cells, tissues, organs and physiological processes that prevent illness and infection.
Table 2-2: Related Body Systems

While these systems have limited or no physical presence in the fist chute, they can affect the overall fisting experience.

Scientific Vocabulary
