- 9.2: Muscles of the Upper Arm
- This page discusses the three main muscles of the upper arm: biceps brachii, brachialis, and triceps brachii. The biceps brachii, located at the front, flexes the forearm and originates from the scapula, inserting on the radius. The brachialis, situated beneath the biceps, arises from the humerus. The triceps brachii, found at the back, extends the forearm and works as an antagonist to the biceps with three origins. Together, these muscles are essential for arm movement and coordination.
- 9.3: Muscles of the Lower Arm and Hand
- This page discusses a lab exercise where students identify and document the muscles of the forearm, including their locations and actions. It features visuals of the forearm and hand muscles and acknowledges its content as licensed under Creative Commons for educational purposes.
- 9.4: Muscles of the Hips and Thighs
- This page provides an overview of gluteal and thigh muscle anatomy, detailing the gluteus maximus, medius, and minimus for posture and movement, the quadriceps for leg extension, the sartorius for its unique shape, and the hamstrings consisting of three muscles, along with the gracilis muscle's position.
- 9.5: Muscles of the Lower Leg and Foot
- This page discusses the anatomy and function of the lower leg, focusing on key muscles such as the gastrocnemius and soleus, which form the calf and enable foot and toe movement. It includes an exercise for identifying these muscles on a model and describes their locations and contractions. Additionally, licensed figures illustrating the muscles of the lower leg and feet are provided.
- 9.7: MODELS- Arm and Leg
- This page provides an overview of human muscles, including their names, actions, origins, and insertions. It categorizes them into groups like forearm movers, hand and finger movers, and thigh and leg muscles, specifically mentioning key muscles such as biceps brachii, triceps brachii, flexor carpi ulnaris, and gastrocnemius. The text highlights their functions in moving and positioning limbs.
