The infraspinous fossa is located on the posterior aspect of the scapula, specifically below the spine of the scapula. It serves as an attachment site for the infraspinatus muscle, which is one of the rotator cuff muscles. This fossa is important for shoulder stability and movement.
What else can I help you with?
Which fossae of the scapula contain muscles that stabilize the shoulder?
Subscapular fossa, Supraspinous fossa, Infraspinous fossa
What are the three fossa of the scapula?
The three fossae of the scapula are the supraspinous fossa, infraspinous fossa, and subscapular fossa. The supraspinous fossa is located above the spine of the scapula and serves as the origin for the supraspinatus muscle. The infraspinous fossa is situated below the spine and provides attachment for the infraspinatus muscle. The subscapular fossa is found on the anterior surface of the scapula and serves as the origin for the subscapularis muscle.
What is the bone containing the supraspinous and infraspinous fossae?
scapula
Where is the spine of the scapula located?
The spine of the scapula is located on the posterior aspect of the scapula, dividing it into the supraspinous fossa and infraspinous fossa. It is a prominent ridge that runs horizontally across the bone and serves as an attachment site for muscles that move the arm and shoulder.
The jaw bone articulates with the temporal bone at what fossa?
The jaw bone articulates with the temporal bone at the mandibular fossa, also known as the glenoid fossa or the mandibular fossa of the temporal bone. This is where the temporomandibular joint is formed, allowing for movements of the jaw.
What is the name of a shallow basin-like depression in a bone?
Fossa = Shallow depression or dip in the surface of a bone Process = Bone marking which stick out from the rest of the bone
What divides the scapula into unequal protions?
The scapula is divided by the spine into unequal portions called the supraspinous fossa and infraspinous fossa. The spine is a bony ridge that runs diagonally across the flat surface of the scapula.
What bone bears the mandibular fossa?
Temporal Bone!
What is the depression on the surface of a bone called?
The depression on the surface of a bone is called a fossa. It is a shallow, basin-like structure that typically serves as an attachment site for muscles or tendons.
How many glenoid fossa in the human body?
Four. The glenoid fossa of each scapula and of each temporal bone.
Is the lacrimal bone and lacrimal fossa the samething?
No, the lacrimal bone is a small, fragile bone that contributes to the bony orbit of the eye, while the lacrimal fossa is a depression on the medial wall of the orbit that houses the lacrimal sac, which is responsible for draining tears from the eyes.
