ANAT 260 Signature Assignment: Anatomical Case Study Analysis

Assignment Instructions 

Answer the following 10 questions using 3 to 4 complete sentences per response. Focus your answers on anatomical structures and use proper terminology to describe locations, relationships, and organization within each system. Be sure to cite your scholarly sources within the text of each response.

Case Study: “The Car Accident” Marcus, a 35-year-old delivery driver, was involved in a minor car accident after another vehicle rear-ended him at a stoplight. He was wearing his seatbelt but felt immediate pain in his chest and lower back. Upon evaluation in the emergency department, he presented with mild bruising across his sternum from the seatbelt, stiffness in his lumbar region, and minor swelling in his left ankle. Marcus also mentioned his vision blurred for a few seconds after the collision, although it quickly resolved.

Questions

Integumentary System: Marcus has bruising across his chest from the seatbelt. Describe the layers of the skin and subcutaneous tissue that may have been affected and identify which layer contains the blood vessels responsible for visible bruising.

Skeletal System: The seatbelt compressed Marcus’s chest, causing pain near his sternum. Identify the anatomical structure of the sternum and name the ribs and joints that articulate with it.

Muscular System: Marcus reports stiffness in his lower back. Identify the major muscles of the lumbar region and describe their anatomical attachments to the vertebral column and pelvis.

Nervous System: The lower back discomfort may involve nerve compression. Identify the spinal nerves emerging from the lumbar region and explain their general anatomical pathway as they exit the vertebral column.

Special Senses (Cranial Nerves): Marcus experienced brief blurred vision after the accident. Identify the cranial nerve responsible for transmitting visual information and describe the anatomical structures it connects between the eye and the brain.

Endocrine System: After a stressful event such as a car accident, the endocrine system responds anatomically through specific glands. Identify one endocrine gland involved in this response and describe its anatomical position relative to nearby organs.

Cardiovascular System: As part of the examination, Marcus’s heart and chest were evaluated. Describe the anatomical location of the heart within the thoracic cavity and identify two major vessels associated with the base of the heart.

Digestive System: Suppose Marcus hadn’t eaten before the accident and later experienced hunger. Identify the major anatomical divisions of the stomach and trace its position relative to surrounding abdominal organs.

Urinary System: Marcus was given IV fluids in the emergency department. Identify the anatomical structures that transport urine from the kidneys to the bladder and describe their position within the abdominal cavity.

Reproductive System: During the routine examination, Marcus’s physician checked for any trauma to the lower abdomen. Identify the major internal reproductive organs of the male anatomy and describe their anatomical relationship within the pelvic cavity.

Question 1: Integumentary System 

Exceeds Expectations Describes all layers of the skin and subcutaneous tissue affected by the bruising and correctly identifies the layer containing blood vessels responsible for visible bruising. Meets Expectations Describes most layers of the skin and subcutaneous tissue affected and identifies some vascular structures. Approaches Expectations Mentions some skin layers but omits subcutaneous tissue or misidentifies vascular layers. Does Not Meet Expectations Provides limited description of affected layers with unclear anatomical details or does not mention correct skin layers or vascular structures involved. This criterion is linked to a Learning Outcome 

 

Question 2: Skeletal System 

Exceeds Expectations Correctly identifies all parts of the sternum, articulating ribs, and associated joints affected by the chest compression. Meets Expectations Identifies most sternum structures and some articulating ribs or joints. Approaches Expectations Mentions sternum structure but omits articulation details. Does Not Meet Expectations Mentions ribs or joints but not their connection to the sternum or does not describe any anatomical structure of the sternum or associated articulations. This criterion is linked to a Learning Outcome 

Question 3: Muscular System 

Exceeds Expectations Accurately identifies all major lumbar muscles and explains their anatomical attachments to the vertebral column and pelvis. Meets Expectations Identifies most lumbar muscles and describes some attachments. Approaches Expectations Mentions muscles of the lumbar region but omits attachment details. Does Not Meet Expectations Mentions only one muscle or provides minimal anatomical explanation or does not identify any lumbar muscles or anatomical attachments. This criterion is linked to a Learning Outcome Question 4: Nervous System Exceeds Expectations Identifies all spinal nerves emerging from the lumbar region and describes their general pathway as they exit the vertebral column. Meets Expectations Identifies most lumbar spinal nerves and briefly describes their anatomical pathway. Approaches Expectations Mentions spinal nerves but provides vague or incorrect pathway details. Does Not Meet Expectations Mentions nerve compression without anatomical identification or pathway or does not mention lumbar spinal nerves or anatomical pathways. This criterion is linked to a Learning Outcome 

Question 5: Special Senses (Cranial Nerves) 

Exceeds Expectations Identifies the correct cranial nerve responsible for vision and accurately describes the anatomical structures connecting the eye and brain. Meets Expectations Identifies the correct cranial nerve but provides limited description of connected structures. Approaches Expectations Mentions cranial nerves in general without specifying the visual pathway. Does Not Meet Expectations Describes partial anatomy of the eye without identifying the correct cranial nerve or does not identify the cranial nerve or visual pathway anatomy. This criterion is linked to a Learning Outcome 

Question 6: Endocrine System 

Exceeds Expectations Identifies one endocrine gland involved in the stress response and accurately describes its anatomical position relative to nearby organs. Meets Expectations Identifies the correct gland but gives a partial description of its anatomical location. Approaches Expectations Mentions a gland but with incorrect function or location. Does Not Meet Expectations Mentions endocrine involvement generally without anatomical detail or does not identify any endocrine gland or anatomical relationship. This criterion is linked to a Learning Outcome 

Question 7: Cardiovascular System 

Exceeds Expectations Describes the anatomical location of the heart within the thoracic cavity and correctly identifies two major vessels associated with its base. Meets Expectations Describes the heart’s general location and names one major vessel. Approaches Expectations Mentions the heart’s cavity but omits vascular details. Does Not Meet Expectations Mentions cardiac anatomy vaguely without cavity or vessel identification or does not describe heart location or major vessels. This criterion is linked to a Learning Outcome 

Question 8: Digestive System 

Exceeds Expectations Identifies all major divisions of the stomach and accurately describes its position relative to surrounding abdominal organs. Meets Expectations Identifies most divisions of the stomach and briefly mentions its anatomical position. Approaches Expectations Mentions the stomach generally without describing its divisions or relations. Does Not Meet Expectations Mentions limited anatomy with unclear or incorrect positioning or does not describe any anatomical structures of the stomach or its relations. This criterion is linked to a Learning Outcome 

Question 9: Urinary System 

Exceeds Expectations Identifies all structures that transport urine from the kidneys to the bladder and describes their position within the abdominal cavity. Meets Expectations Identifies most urinary structures but with limited anatomical positioning. Approaches Expectations Mentions structures of the urinary system without spatial orientation. Does Not Meet Expectations Provides partial or vague description of urinary structures or does not identify urinary anatomy or positioning. This criterion is linked to a Learning Outcome
