Zoology: Form and Function (BIO 3400) Name_________________________ Lab Tutorial Assignment Zoology Lab Tutorial Assignment The goal of this short tutorial exercise is to orient you to the types of assessments and submission methods used in this section of Zoology. Each of the lab exercises this semester will combine surveys of specimens, structure identification, and relation to lecture material. Part 1 – Dissection techniques and safety: Since Zoology is often taken by students with minimal dissection experience but we need to begin working with specimens quickly – please watch the following short videos and answer the questions. Video from BlueLink on dissection types (runtime 1:59seconds: https://www.youtube.com/watch?v=-_B17pTmzto 1) What is the primary difference between sharp and blunt dissection? The primary distinction between sharp and blunt dissection lies in the methodology and instruments employed to navigate tissue separation. Sharp dissection relies on surgical tools with sharp edges, such as scalpels or scissors, to meticulously cut through tissues along defined planes, ensuring precise incisions and minimal collateral damage. In contrast, blunt dissection involves the use of blunt instruments, like forceps or fingers, to gently push tissues apart without cutting, emphasizing a delicate approach to tissue separation. While sharp dissection is favored for procedures requiring precise incisions, such as surgical operations or detailed anatomical dissections, blunt dissection is preferred in situations necessitating the preservation of delicate structures, such as neurosurgery or dissections involving fragile tissues, where cutting may result in unintended damage. 2) What are the advantages to using blunt dissection? Video from BSMS anatomy intro on lab safety and scalpel technique (Watch only until 3:50): https://www.youtube.com/watch?v=7D8Y5VosVxU 1) We will be using more traditional forceps in our dissections – but why is the use of forceps and probes so important? Blunt dissection offers several advantages in surgical and anatomical procedures. Firstly, it allows for a gentle approach to tissue separation, reducing the risk of inadvertent damage to delicate structures such as nerves, blood vessels, and organs. This is particularly advantageous in surgeries where preserving surrounding tissues is crucial for optimal outcomes. Additionally, blunt dissection minimizes bleeding and tissue trauma compared to sharp dissection, leading to reduced post-operative complications, faster healing, and improved patient recovery. Moreover, blunt dissection can be performed using readily available tools such as forceps or fingers, eliminating the need for specialized equipment and reducing procedure costs. Overall, the careful and controlled nature of blunt dissection makes it a valuable technique in various surgical and anatomical contexts, contributing to safer and more efficient procedures

Making small shallow cuts is important in various contexts, particularly in surgery. In surgery, small shallow incisions minimize tissue trauma, reduce bleeding, and promote faster healing. They also contribute to better cosmetic outcomes, as smaller incisions result in less scarring. Overall, making small shallow cuts is essential for achieving accuracy, minimizing damage, and optimizing results across various tasks and disciplines Video from BlueLink on reflection and retraction (Watch only until 2:05) https://www.youtube.com/watch? v=g4ja6fjSzo&list=PLN2fodvzfTGHthaIe9um__ZdxiaZV75i1&index=6&t=0s 1) What is the difference between reflection and retraction? Reflection involves lifting or folding back tissues to expose underlying structures, providing better visibility, while retraction entails pulling tissues away from the surgical site without folding them back to create space and improve visualization. 2) What is the benefit, during dissection, to reflection versus retraction? Reflection during dissection involves folding tissues back to expose underlying structures, allowing for better visibility and access to the surgical site. This method provides a clearer view of anatomical landmarks and facilitates precise dissection around critical structures. On the other hand, retraction involves pulling tissues away from the surgical area without folding them back, creating space and improving visualization by widening the operative field. Both techniques are essential in different scenarios during dissection, depending on the specific surgical goals and anatomical structures involved. Anatomical terminology and biological directions (Runtime 9:21): https://www.youtube.com/watch?v=kvHWnJwBkmo 1) Why use biological directions instead of visual description? Using biological directions, such as dorsal, ventral, medial, and lateral, provides standardized and precise terminology for describing anatomical relationships and positions within the body. This terminology is universally understood among healthcare professionals, researchers, and anatomists, ensuring clear communication and accurate interpretation of anatomical structures regardless of language or cultural differences. In contrast, visual descriptions can vary depending on the observer's perspective and may lead to confusion or ambiguity. Biological directions offer a systematic and consistent framework for communication in medical contexts, enhancing accuracy and facilitating effective collaboration among healthcare providers. 2) Anterior/posterior and superior/inferior are useful for humans but can get confusing for other types of animals? 1) what is the difference between the two sets of words and 2) why might that be hard to clarify in other types of animals?

Zoology: Form and Function (BIO 3400) Name_________________________ Lab Tutorial Assignment The terms anterior/posterior and superior/inferior are anatomical directional references commonly used to describe positions and orientations within an organism's body. Anterior refers to structures closer to the front or head end of the body, while posterior refers to those nearer to the back or tail end. Superior denotes positions above or closer to the head, whereas inferior describes positions below or nearer to the tail. However, these terms can be challenging to clarify in other types of animals due to variations in body structures and orientations. In animals with horizontal body alignments or non-standard anatomies, such as quadrupeds or aquatic species, the distinctions between these directional terms may not be as intuitive, making their application more complex 3) The concepts of proximal/distal and medial/lateral are similar but focus on different parts of the body. Compare and contrast the two sets of terms. Proximal/distal and medial/lateral are both pairs of anatomical directional terms used to describe positions or locations within the body, but they focus on different aspects. Proximal and distal refer to distances relative to a reference point or origin. Proximal denotes positions closer to the point of attachment or center of the body, while distal indicates positions farther away from this point. On the other hand, medial and lateral describe positions relative to the body's midline. Medial refers to structures closer to the midline or center of the body, while lateral indicates structures farther away from the midline or toward the body's sides. While both pairs of terms provide spatial orientation within the body, proximal/distal focus on distance from a reference point, whereas medial/lateral focus on positions relative to the body's midline. 4) Name and describe the planes of the human body described in the video. Sagittal- lengthwise cut that divides the body into left and right portions Frontal- sideways cut that divides the body into anterior and posterior portions Transverse- horizontal cut that divides body into superior and inferior portions Oblique- oblique angle 5) How do you think we might need to adapt some of the language from this video since we’re not JUST thinking about humans in Zoology? When considering anatomical anatomy in zoology, we need to adapt the language used in the video to encompass a broader range of organisms beyond just humans. Instead of focusing solely on human-specific terms and structures, we should use more general terminology that applies universally across different animal species. By using terminology that is applicable to a wide range of organisms, we ensure that our discussions and analyses in zoology are comprehensive and relevant across diverse animal taxa Part two – Submission of lab sheets to blackboard: Each week you will need to submit your lab assignments to blackboard. These will include a copy of the lab handout completed for each person and ONE photo sheet collected by your group that contains pictures of all specimens used in lab. For this week this handout will serve as the lab handout BUT to get the points associated with it you must submit a photo taken by you (cell phone photos are fine!) of any animal put into a word
