For the assignment, students are expected to perform various activities related to joints, muscles, bones, and related anatomy, including answering theoretical questions and demonstrating physical movements. The tasks involve identifying joint types, muscle groups, bony structures and markings, performing movements to demonstrate joint actions, analyzing depreciation and amortization calculations for assets, recording journal entries for various transactions, and calculating dividends and goodwill. There are also practical components such as virtual labs on the skeletal system, and exercises involving drawing or taking pictures of movements.

Students are required to answer specific questions about joints, muscles, and bones with precise calculations for financial and accounting scenarios. Proper submission involves typing answers and including all relevant pictures directly within a Word document, submitting via Blackboard in the specified format. Late submissions or incorrect formats will result in penalties or non-acceptance. The assignment emphasizes detailed, accurate responses with appropriate citations for referenced materials.

Introduction

The human musculoskeletal system is a complex framework that provides support, allows movement, and protects vital organs. Understanding joints, muscles, and bones is essential not only for anatomy and physiology but also for applications in medical fields, physical therapy, and biomechanics. This comprehensive paper explores the anatomy of joints and muscles, incorporating both descriptive and analytical perspectives, alongside financial accounting principles applied through related exercises. Emphasis will be placed on key joint types, muscle groups, bone markings, and their functions, supported by calculations related to asset depreciation, amortization, and financial transactions.

Joints and Muscles Anatomy and Function

The human body's mobility largely depends on the articulations between bones, known as joints, and the muscles that facilitate movement. The joints are classified into three primary types: fibrous, cartilaginous, and synovial, with each serving different functions and degrees of mobility. The recognition and understanding of these joints are vital for diagnosing injuries and understanding biomechanics.

Cartilaginous Joints

Cartilaginous joints are connected entirely by cartilage and provide limited movement, serving as pivotal points in growth and stability. The anterior joint uniting the two halves of the pelvis is the pubic symphysis, which is a fibrocartilaginous joint. During childhood, immovable cartilaginous joints such as the epiphyseal plates (growth plates) are present, which ossify in adulthood to become synostoses.

Synovial Joints and Their Movements

Synovial joints are highly movable joints classified by the type of movement they permit:

  • Plane joints (e.g., intercarpal joints) allowing gliding movements.
  • Hinge joints (e.g., elbow) permitting flexion and extension.
  • Pivotal joints (e.g., atlantoaxial joint) allowing rotational movement.
  • Condyloid joints (e.g., wrist) allowing biaxial movement including flexion, extension, abduction, and adduction.
  • Saddle joints (e.g., thumb) permitting opposition and other movements.
  • Ball-and-socket joints (e.g., shoulder, hip) providing the widest range of motion, including rotation.

Actions at Joints and Muscle Function

Specific movements at joints depend on muscle groups acting across these joints, with actions including flexion, extension, abduction, adduction, elevation, depression, protraction, retraction, inversion, eversion, supination, and pronation.

For demonstration purposes, typical movements can be physically performed: flexion/extension at the elbow, abduction/adduction at the shoulder, elevation/depression at shoulder girdle, protraction/retraction of the jaw or scapula, inversion/eversion at the ankle, and supination/pronation at the forearm.

These movements involve various muscle groups, for example, the biceps brachii and triceps brachii for elbow movement, the deltoid for shoulder abduction, the masseter for jaw elevation, and the tibialis anterior for dorsiflexion of the foot.

Bone Markings and Skeletal Anatomy

Bone markings such as projections (e.g., tubercles, tuberosities), holes (e.g., foramina), and depressions (e.g., fissures) serve as attachment points for muscles, ligaments, and blood vessels, or as passageways for nerves. Recognizing these markings, such as the acromion process, glenoid cavity, and greater trochanter, aids in understanding skeletal attachments and joint articulations.

Calculations and Financial Accounting

Asset Valuation and Depreciation

In scenarios involving asset valuation, depreciation, and amortization, precise calculations are critical. For example, when allocating the cost of a lump-sum purchase, the relative appraised values are proportionally assigned to each asset—land, building, and equipment. The depreciation expense under the double-declining balance method accelerates depreciation in early years, calculated as 2 times straight-line rate multiplied by book value at the beginning of each year.

Similarly, straight-line depreciation spreads cost evenly over asset’s useful life. For intangible assets like patents, amortization expense is derived by dividing the initial cost minus residual value over the expected useful life.

Journal Entries

Recording transactions such as asset purchases, asset disposals, and stock issuance requires precise journal entries. For example, issuing stock involves crediting common stock account with the par value and the balance to paid-in capital in excess of par, while purchasing assets requires debiting the relevant asset account and crediting cash or accounts payable.

Concluding Remarks

The integration of anatomical knowledge with financial principles demonstrates the multifaceted skills needed in medical and business professions. Accurate identification and understanding of joints, muscles, and bones enhance comprehension of human physiology, while mastery of financial calculations ensures proper asset management and reporting. Together, these disciplines contribute to a holistic understanding of health sciences and economic management.
