Skeletal System and Appendicular System Overview

Overview of the Skeletal System

• Introduction to the skeletal system exam schedule

  • Exams are held after each chapter on incorporated systems

  • Last exam covered the integumentary system, tissues, elements, and cells

  • Upcoming exam focused on the skeletal system, particularly joints

Joint Treatment and Study Plan

• More focused study on the skeletal system, particularly joints

  • Additional session for conditions affecting the skeletal system

  • Importance of understanding normal vs abnormal physiology

  • Introduction to the concept of pathology as comparing normal and abnormal conditions

• Structure of the course leading up to the exam:

  • Review scheduled after each system, specifically for the skeletal system

  • Mention of dates:

  • Next Friday (in a week) and following Monday (no class for Easter)

  • Monday emphasizes the first section of joint study

  • Wednesday to cover the second section of joints with a review afterwards

  • Noted that pathology overview may be skipped due to timing

Appendicular System Focus

• Review of the appendicular system

  • Pectoral girdle previously studied with practical demonstrations (manikins)

  • Current focus on pelvic girdle and lower limbs

Pelvic Girdle Anatomy

• Discussion of pelvic girdle composition

  • Comprised of a pair of bones similar to the pectoral girdle

  • Connects with the sacral bone at the auricular surface

  • Discusses importance of pelvic shape variations between genders

  • Female pelvic girdle: wider for childbearing

  • Male pelvic girdle: more narrow shape

• Importance of pelvic girdle in physiological functions:

  • Supports pelvic organs (uterus in females, prostate in males)

Hip Bone Composition

• Structure of the hip/pelvic girdle

  • Formed from three fused bones:

  • Ilium: large, uppermost bone (beige or salmon colored)

  • Ischium: lower, seating area bone (blue)

  • Pubic Bone: anterior bone meeting at the pubic symphysis

  • Palpation locations for physical examination of each bone part

  • Note on potential pain sources from attachments of muscles, ligaments, and tendons

  • Introduction to bursitis: inflammation leading to fluid accumulation between tendons and ligaments

Hip Bone Specifics

• Mention of anatomical landmarks of the hip bone:

  • Anterior and Posterior Spine: sides of the pelvic girdle

  • Iliac Crest: felt on the side of the body

  • Acetabulum: socket for the femur joint

  • Obturator Foramen: hole in the hip bone

  • Greater Sciatic Notch: protruding area felt around the buttocks

  • Iliac Fossa: concave area of the ilium

  • Auricular Surface: connection point with the sacrum

  • Pubic Symphysis: joint formed by the pubic bones

Differences in Male and Female Pelvic Girdle

• Visual and functional differences explained:

  • Female Pelvis: wider openings and less prominent ischial spines

  • Male Pelvis: longer sacrum and narrower subpubic arch

  • Enhanced childbirth capacity referenced

Lower Limbs Anatomy

• Overview of lower limb categories:

  • Thigh Bone: called femur (longest and heaviest bone in the body)

  • Leg Bone: specific name not provided in this section

  • Foot Bones: specific names not provided in this section

Details on the Femur

• Anatomy of the femur as a long bone

  • Contains a shaft and a head with a fovea capitis notch for vascular attachment

  • Greater and Lesser Trochanters: important projections for muscle attachment

  • Patellar Surface: accommodates the knee cap (patella)

  • Medial and Lateral Epicondyles: rounded prominences at the sides of the knee

  • Linea Aspera: a ridge along the shaft providing surface area for muscle attachment

  • Goodial Tuberosity: specific location relevant for physical examination noted

Conclusion

• Summary of skeletal system anatomy and related study topics for evaluation

• Encouragement for students to prepare for the upcoming exams and absorb detailed information about the skeletal system and its components
