ATI TEAS Science Questions
1. Which of the following arteries are not branches of the facial artery in the cervical portion?
- A. Ascending palatine artery
- B. Glandular artery
- C. Superior labial artery
- D. Tonsillar artery
Correct answer: C
Rationale: The correct answer is C, the Superior labial artery. It is a branch of the facial artery in the facial portion, not in the cervical portion. The ascending palatine artery, glandular artery, and tonsillar artery are branches of the facial artery in the cervical portion. The ascending palatine artery supplies the palate, the glandular artery provides blood to the salivary glands, and the tonsillar artery is responsible for supplying blood to the tonsils. These arteries play a crucial role in the vascular supply of the head and neck region, aiding in various physiological functions.
2. Which type of tissue is characterized by tightly packed cells with minimal extracellular matrix and provides structural support and protection?
- A. Epithelial tissue
- B. Connective tissue
- C. Muscle tissue
- D. Nervous tissue
Correct answer: A
Rationale: Epithelial tissue is the correct answer as it aligns with the description provided in the question. Epithelial tissue is characterized by tightly packed cells with minimal extracellular matrix, which allows it to form protective barriers on the body's surface and line internal organs, providing structural support and protection. Connective tissue, while important for support and connection between tissues and organs, does not fit the description in the question of being tightly packed with minimal extracellular matrix. Muscle tissue is responsible for movement, and nervous tissue transmits signals throughout the body, neither of which are primarily involved in providing structural support and protection as described. Therefore, based on the characteristics described in the question, epithelial tissue best fits the description of tissue that provides structural support and protection.
3. The spleen, a large lymphatic organ, is located in the:
- A. Chest
- B. Abdomen
- C. Pelvis
- D. Head and neck
Correct answer: B
Rationale: The spleen is located in the abdomen, specifically in the upper left part of the abdomen, under the ribcage and above the stomach. It is an important organ in the lymphatic system responsible for filtering blood, storing blood cells, and fighting infection. It is not located in the chest, pelvis, or head and neck regions. Therefore, the correct answer is 'B: Abdomen.' Choices 'A: Chest,' 'C: Pelvis,' and 'D: Head and neck' are incorrect as the spleen is not situated in these anatomical areas.
4. Which part of the brain is responsible for processing vision?
- A. Occipital lobe
- B. Frontal lobe
- C. Temporal lobe
- D. Parietal lobe
Correct answer: A
Rationale: The occipital lobe is the part of the brain responsible for processing visual information. Located at the back of the brain, the occipital lobe contains the primary visual cortex, which plays a crucial role in interpreting visual stimuli received from the eyes. The frontal lobe is primarily involved in higher cognitive functions, decision-making, and motor control, not vision processing. The temporal lobe is responsible for auditory processing, memory, and emotion, not vision. The parietal lobe is involved in sensory integration, spatial awareness, and perception of stimuli, but not specifically for visual processing.
5. Which type of joint allows for the greatest range of motion?
- A. Hinge joint
- B. Ball-and-socket joint
- C. Pivot joint
- D. Saddle joint
Correct answer: B
Rationale: The correct answer is B: Ball-and-socket joint. The ball-and-socket joint, like the shoulder joint, allows for the greatest range of motion due to its structure, enabling movement in multiple directions. In contrast, hinge joints, pivot joints, and saddle joints have more restricted ranges of motion compared to ball-and-socket joints. Hinge joints primarily allow movement in one plane, pivot joints allow rotation around a central axis, and saddle joints have limited movement compared to ball-and-socket joints.
