Study Notes

Anatomy of the Nasal and Oral Structures

Hard palate forms the roof of the mouth; consists of nasal floor structures.
The nasal septum, made of the vomer bone, divides the nasal cavity into left and right sides.
Superior and middle conchae are bony shelves projecting into the nasal cavity from the ethmoid bone.
Maxilla, consisting of two bones, forms the upper jaw, part of the hard palate, lateral walls of nasal cavities, and floors of orbital cavities.

Appendicular Skeleton Overview

Comprises two pairs of limbs and two girdles: pectoral and pelvic.
Pectoral girdle (shoulder) connects upper limbs; pelvic girdle secures lower limbs.

Upper and Lower Limbs Structure

Upper limb consists of three segments: arm (upper), forearm (middle), and hand (lower).
Lower limb also consists of three segments: thigh (upper), leg (middle), and foot (lower).

Key Features of the Clavicle

Acromial extremity articulated with acromion process of the scapula.
Conoid tubercle is an attachment point for ligaments, with a tapering body along its length.
Deltoid tuberosity and radial groove are important landmarks on the humerus.

Pelvic Girdle Composition

Known as the "hip girdle," attached sturdily to the axial skeleton (sacrum).
Consists of paired hip bones leading to a stable framework compared to the pectoral girdle.
Bony pelvis includes the hip bones, sacrum, and coccyx.

Childhood Development of Hip Bones

Hip bone (os coxae) consists of three separate bones that fuse during childhood: ilium, ischium, and pubis.
False pelvis lies above the pelvic brim and supports abdominal contents; aids in supporting the uterus during pregnancy.

Differentiation of True and False Pelvis

True pelvis is located below the pelvic brim, defined by the pelvic inlet and outlet.
The pelvic outlet is defined by the coccyx, ischial tuberosities, and pubic arch, forming the boundaries for childbirth.

Male vs. Female Pelvis

Male pelvis is generally narrower and taller while female pelvis is wider and shorter to facilitate childbearing.
The differences in shape and size are critical for understanding childbirth dynamics.
